A Little Night Wrenching - Conclusion

At long last the radiator is in and the truck is up and running. As I said in the last post, sometimes the gremlins teach you the meaning of pain. That was the theme of this job.

I've been working on this old truck for many years and in all that time I've never really had problems with broken fasteners. The only other one I can remember is one that held on an access plate under the front of the engine. In that case I still had three good fasteners and it was only holding a small plate. I didn't repair it.

In this case, two of the broken bolts attach the steering damper to the frame. Being unwise to live without the steering damper, I had no choice this time.

The other broken bolt is one of four that hold the driver's side headlight assembly. I probably could have gotten away without that one, but since I was setting up the bolt-drill-out shop, I figured I might was well get that done too.

In all I fixed three holes and managed to drill none of them straight through. They all ended up being off center and at some angle. For the two large holes, I think I removed about 1/4 of the threads, but the bolts went in easy (after chasing with the tap) and took the torque I put on them.

The next picture is at an intermediate step. The holes to be repaired are the right and left holes. The middle hole is not part of the project. You can see that for the right hole, at this intermediate step, it was pretty much centered. For some reason when I went up to the final size the bit dove to one side and ended up way off center. The picture below is of the fastener after I got it out. you can see how far off center it was.

The other fastener was much more stubborn. Even after I drilled the final size, the remnant was still locked into the nut. I had to eat away at it using a carbide bit in my Dremel-dentist fashion. There wasn't a big enough piece left to photograph. This operation unfortunately cost me two expensive Dremel carbide bits.

The smaller bolt (for the headlight) was a little more challenging because it was harder to reach. It was pretty far inside so I had to come up with a long extension. I had this hex shank extension for those quick change bits and I found this little drill chuck that I could use with it. My only complaint about the little chuck is that it wasn't very strong and this 5mm drill slipped more than I thought was ok.

When it comes to working on cars, extensions are golden. Over the years I've collected quite a number of them including a 24" 3/8" drive and a 16" 1/4" drive. There's also this 12" hex shank adapter. These combined with all the little adapters and universal joints make the work go so much easier.

The last major hurdle in this job was that the new radiator´╗┐ did not fit well. It was about 3/16" too wide. that doesn't seem like much, but it's enough to prevent it from fitting without modification. I had to grind the mounting brackets as well as the mounting holes.

I did not end up putting in the power steering cooler, but I have figured out how it's going to go in and I'll do that later this summer. Taken with all the extra repairs and modifications I figure this job took about twice as long as it would have otherwise. On the up side, I got a bunch of new drills and taps and that cool little drill chuck out of the deal. Not to mention the satisfaction of success hard won. Even considering all the extra tools I had to buy, I still only paid out about a third of what it would have cost at a shop. Of course, when you weigh that against the amount of time it ended up taking, your cost-savings argument is destroyed. But as we determined in the last post, it's not about the money.

A Little Night Wrenching

I like to wrench, and that can be difficult to work in around raising toddlers and the other business of life. That's why it ends up being done at night. Toddlers give you no peace when they know you're out in the garage using tools and they are not, so you find yourself waiting until they are unconscious.

So anyway, last week while I was on an outing with the scouts I came into some power steering trouble with the Land Cruiser. About six years ago I replaced the entire power steering system except for the fluid cooler. That cooler finally gave it up. While correcting the problem (temporarily) I discovered bubbles and fluid coming from the radiator.

As Jeff Foxworthy once said, if things seem to be going smoothly, you're obviously overlooking something. And so it goes with car problems. I found the coolant level to be much lower than I thought, and that just highlights the importance of checking the fluids regularly.

A while ago a mechanic said I should replace the radiator. I actually agreed with him, but I didn't want to do it right away. I knew it would have to be done sooner or later, so when I found what I found, it wasn't really a surprise.

This project has been memorable in several ways. It has gone fairly sideways in some respects. Also, I have to open more systems than normal, simply because of how they all relate around the radiator. This is my third radiator done shadetree-mechanic style. When I was about 18 I did it on my 1989 Mazda 323. I did the whole thing in about four hours. The next one was in the summer of 2007 when my 1986 Toyota SR5 Pickup barely made it home. I'll probably end up taking as long to do this one as both of those took together.

This truck has a transmission oil cooler built into the radiator, so swapping it requires opening both the coolant system and the transmission oil cooler circuit. Add to that the extra restorations that are required of the power steering system, and the project scope begins to creep up.

In the next picture, you can see the inlet and outlet of the transmission cooler at the bottom of the radiator. On the floor to the left you can see the new aftermarket power steering cooler. Using an aftermarket one saved me $300.

I have been surprised at the level of disassembly that has been required. On the others I didn't remember having to basically remove everything from the front that I could.

Here's the new thermostat just before closing it back up in there.

Now, you may be asking what had gone sideways? Well, I sheared off three bolts and rounded one nut. The nuts pictured below came loose for the most part, but the last one rounded off and was being utterly unyielding. I looked over Youtube and found a great technique for rounded nuts that only involves the judicious application of a small cold chisel. This method worked great.

Those three bolts that I sheared off are going to be more problematic. I still haven't dealt with them, but I do have the plan outlined. One of them I could live without. It is one of four that hold the headlight assembly on. The other two are both of the mounting bolts that attach the steering damper to the frame. I can not drive without the steering damper, so I will have to sort that out before calling the project complete.

Now, I have never actually done this. I came close on my motorcycle project where I had to repair a sheared bolt. That one had some very challenging tight space restrictions. These ones are relatively open, but they will be difficult because I have to either extract the bolt or drill it out by hand, which means I have very little room for error. Today I bought some drills and taps to that end. I'll test my mettle on Monday. That will be the very last step because that piece is basically the last one to go together.

This is a good place to insert a plug for PB Blaster. I didn't give these bolts long to soak under the PB Blaster, but others I did came off just fine. If you plan to work on a car that is more than a couple of years old, go buy the PB Blaster. It will save you lots of heartache.

So, sometimes you start out thinking it will be really hard, but it turns out to not be so bad. Sometimes you start out thinking it will be easy, and the gremlins teach you the meaning of pain.

So why do I do it? What draws me to this self-abuse, if you want to call it that? I'm not sure. It would be tough to make the argument that I'm doing it to save money, although I do save money. I think I do it because I love to learn. I always finish a project with more knowledge than I had at the outset. I also derive a lot of satisfaction from repairing things.

I also think I do it to stay grounded. In my job I spend a lot of effort telling mechanics how to do work. Things look a lot different from your cubicle than they do when you open the system and get an adrenaline rush because water is just gushing out in front of you. It's difficult to describe the feeling when that bolt twists under your wrench and you know that it's head is coming off. Your stomach just sinks a little. In those cases, there usually is nothing for it. Since they don't let me turn wrenches on the ships, I have to do it in my driveway, and that's just fine by me.

Sweet Ride

Look at this...

This is a 2016 Honda Pilot.

I have never bought a brand new car in my life. Heck, I've never even wanted a brand new car. I know a lot about working on cars so I feel like I can leverage my skills and save money by buying older cars that have demonstrated quality.

I bought my first Toyota with 155,000 miles and my second with 154,000. We bought our CR-V with 94,000. Most people consider cars spent at that point. But not me. My Landcruiser is 22 years old and runs better today than it did when I bought it.

The point is, I like older cars because I feel like I get more value from it. I also get satisfaction from getting my hands dirty under the hood. My first truck (the Toyota), I owned for five years and I sold for only $1,500 less than I paid for it. And in that time I had my first experiences with changing a transmission (me and a buddy in the driveway), oil leaks, and disassembly and reassembly of front four wheel drive hubs.

I balk at the cost of warranties because I feel like the effort and heartburn associated with obtaining warranty service is just about on par with simply doing the work. This is particularly true with older cars that have some sort of third party or non-manufacturer warranty. These are uniformly designed with the interests of the warranty provider's bottom line at heart rather than providing service. (If I bought a brand new car, I would gladly accept the manufacturers warranty.)

Some say that cars are too smart to work on any more. To me it's an opportunity to get smarter, not roll over and concede defeat. The basic functions are the same, there's just some extra systems to help it along.

So why would I even consider a brand new car?

Maybe you didn't see picture. Look at it again.

That's a hot ride. It looks like a larger version of the CR-V, which I love. I've always liked the CR-V, but never more than the current model. In my mind, though, the chief failing of the CR-V is it's light carrying capacity and its small size. It fits the niche that it's designed for very well, I just want something that looks like it but has higher towing capacity, and it would be great if it had third row seating. Also, I'd like to see some suspension upgrades that would make it more stable under heavy loads.

I've essentially just described the 2016 Pilot. The availability of suspension upgrades is still slim, but it is brand new.

This new model also overcomes previous Pilot's chief drawback: its looks.

I'd love to drive one home today.

Don't misinterpret this to mean that I'm about to buy one of these magnificent beasts. It's simply a financial impossibility to drop $36,000 on a car right now. And then there's the philosophical implications of putting two car seats, their occupants, and a furry beast into this lap of luxury. It already makes me cringe to put them all into an 8-year-old CR-V with 120,000 miles.

Anyway, philosophy aside, its not going to happen. What's new here is the desire to have this brand new car. It's not something I'm accustomed to. Maybe in a few years I'll be able to pic up a nice used one.

Some Spring Camping

So this weekend we had planned on going on a scout outing. Fate, however, had other plans and the outing was rescheduled to a weekend I can't attend. Since the outing was to Tubal Cain Mine and the plane wreckage, I felt I needed a make-up tent night. (Don't have time for the hike.) Here's a confession, part of the reason I was so anxious for a night out is I just bought a new tent and was desperate to take it for a spin.

Since the outing was rescheduled, I was also able to attend a wedding reception I wanted to go to. So there you have it, cram in a night in a tent while also attending a reception.

Fortunately, I have both a willing co-conspirator and a very nearby campground, so we made it happen. The outing was pretty simple because we only had a little time, but it covered all the main bases. We had a fire, roasted some marshmallows, and then the kiddo decided to it was time to go to bed. All in about 35 minutes.

Of course, he was tired until we got into the tent, then he was too hyper to calm down. Lately I've been reading Roughing It at bed time, so that helped a little. It was also fun to text with mommy at bedtime, reading him the texts and texting what he told me to.

Of course, when you go camping, the only thing better than going to bed late is getting up early. Around 6:00 he decided it was time to get up. So we wrapped it up early. He finally got me up at about 7:15. We started the fire back up and had some muffins and juice boxes. After a few minutes he decided he was cold and started packing up.

The whole thing wrapped and we were home by 8:45. Camping with toddlers. Can you beat it?

Kitchen Work (A couple steps closer)

This weekend I made a strong push to get the kitchen backsplash tiled. And tonight I was planning to blog about it, but instead I had to spend an hour dinking around with my blogger account. The details of that are frustrating but irrelevant. So much for a quick blog post and off to bed.

Friday after work I decided I wanted to do this since I've been procrastinating it for some time. (It's even on my "Procrastination List"--an actual thing--not made up.) So we headed up to Home Depot so I could buy the rest of the material and rent the tile saw.

Then I went home, put the kids to bed, and started cutting. The first two pictures were taken during this time while I was cutting the tiles and laying them out on the garage floor. Chelsea was good enough to clear off the counters and get it all ready for me to work. It's kind of an adventure when you close the kitchen for two days.

For this project I decided to go with SimpleMat, a product made by Custom Building Products. When I did the bathroom, I used a product called Bondera that worked in a similar way. I was also using Fusion Pro grout (another one from Custom Building Products), which is the same grout I used on the floor with good success. The SimpleMat was easy to set up, although it was not very easy to handle while cutting since it is very sticky. Of course, I wouldn't want it any less sticky. Don't be ridiculous.

This product is designed to be grouted immediately after placing the tile. This makes for a long day, but also means you can get it done in one day.

I added some extra tape support for the nosing on the top just to make sure it would stay put while I grouted.

One difficult thing about the Fusion Pro grout is that it dries pretty fast. Being that it's an epoxy grout, this can mean you won't be able to get it all the way off. This back corner was my first area. It didn't go well at first. Fortunately, I was able to get it to clean up a little afterward with some haze remover and the handy Dremel Multimax.

Having done a small amount of tile wherein I relied heavily on the Multimax, I'm left to wonder how tile work was done before they were invented. I cleaned up the excess using the grout removal tool and then put a scotch-brite pad wetted with haze remover on the sanding attachment. It improved matters tremendously.

Here it is after all the grouting and cleanup was done. In this picture I still had to caulk, but it's almost there.

Here are some detail shots after the final caulking. I'm pleased with the result.

Now my procrastination list is down by one.

Well, I missed something funny.

My last post about the Not So Big House was published on January 22, 2016.
My first post "By way of introduction" was posted on January 22, 2006.

Way to miss a golden opportunity.

Anyway, Thanks for reading.

The Not So Big House

Recently I've been exploring the idea of building my next house. Ever since I completed a high school vocational training class that built a house, I've thought it was something that I wanted to do some day. And now, with a growing family, sometimes it feels like that "some day" may have arrived.

As a part of my study I've picked up "The Not So Big House" by Sarah Susanka. This is not a really new book (it was originally published in 1998) but in that time it's ideas have gained a great deal of traction. It was early to the sustainable building movement that is now alive and well, particularly in the pacific northwest.

I've come across many ideas in this book that I need to process, hopefully to help me be able to translate them into something I might be able to use. So, as I've said before, this blog is for me, but if you'd like to listen in on my inner monologue, have at. You've been warned.

Quality > Quantity
First off is the concept of quality over quantity. This resonates strongly with me. I value, well, value above all else. I can not bear to spend anything over what is necessary. For me the greatest satisfaction is in finding that sweet balance between cost and utility. This can apply to anything. It can be monetary cost, time spent, effort spent, etc. And utility can come in many forms as well. Is the solution useful, attractive, and functional? I often look to see if just a little extra effort or cost will produce a demonstrably superior result. When that little effort is worthwhile, I can not bear to not make the extra effort or expense. Often, when I'm shopping for something I'll do a good deal of research and determine the minimum quality I'm willing to accept and then wait for a price I can live with. I'd rather do without than live with less-than-ideal. Of course, this is the ideal. Sometimes I am pressed into a corner. It's life. It happens to all of us.

As applied to a house, this makes sense. This is the same idea that you find in those little setups at Ikea. Those help you to see that you might actually be able to live in 500 square feet if it was laid out cleverly.

Not with children, though. You can't live with children in 500 square feet. Can't be done.

Use Space Sparingly
All space in a home should be considered carefully. I've already looked at hundreds of stock floorplans and it is very apparent that they are not all created equal. I've seen a particular plan that is over 2400 square feet, and yet has only three bedrooms. Each room has it's own bathroom and expansive closet. The master closet is slightly small than my current master bedroom. At first I liked this plan, but after I looked at it for a while (and before this reading) I decided I would not be satisfied with it. There is an almost identical four bedroom plan, and even with four bedrooms, it was....gluttonous.

That sent me back looking carefully at my own home. I like what I have. Part of that is because I don't feel like there's a lot of extra stuff. Again, this comes down to that balance between cost and utility. I see space as a cost, since you have to spend to get it, and utility is how well that space fits your life. I like my house, but there are a few shortcomings. I won't go into them here, but I feel like they could be addressed by only adding a few hundred square feet to what I already have.

Formal Rooms
Formal rooms are a holdover from a past that no longer exists. Most people today will tell you they hardly ever use their formal dining room or living room. Sure Thanksgiving is there (if you're not at grandpa's house), and sometimes friends come over. But how many friends of yours sit in the formal living room? This idea was kind of a big deal in 1998, but now many homes are built with large great rooms that include the kitchen space. For me this is ideal. When you're family comes over you all end up in the kitchen anyway. This also reflects how most people live today. The family spends time together in the family room (or great room) and having the kitchen as a part of or appendage to that space is only natural.

Visual Connection
If you can see another area in the home, you feel connected to it, while at the same time long interior views make the home feel larger. One manifestation of this is the concept of the away room. This is an area that is acoustically isolated from the great room, while still being close enough to feel nearby and connected. Often it is separated from the great room by french doors with glass. This allows it to be visually connected, and still enjoy some separation.

Up until I read this, I was using the word "library" to express what I thought I needed. I wanted space for study, reading, & music that could be nearby but separated from the confusion of the great room. One of the things my current house lacks is space for books. Recently there has been some writings about how the necessity of a home library is greater than ever, and deliberately creating a space of good old-fashioned paper learning is critical, even given easy access to electronic information. I fully subscribe to this. I love Google Maps, but I miss pulling out that gigantic world atlas and leaning over it on the table.

The idea of connecting this space visually to the rest of the house was new to me, but it fits perfectly.

Ceiling Heights
Ceiling heights can dramatically impact the way a space feels. This turns out to be in relation to the dimensions of the room: larger rooms can tolerate having higher ceilings. I had never thought of this, but again, it fits perfectly. The ceiling should be lower in spaces that should be cozier. Think of places like that away room, the bedroom, or a window seat. If the volume of a space is smaller, it can actually feel more sheltered. Think about how children like to play in little nooks that are scaled to their size. Adults have that same involuntary draw toward safety, but we're better at denying it in favor of what we think we want.

This is manifest in many vacation homes. It's not unusual to see vacation homes with low ceilings in some areas, such as the dining nook, or the bathrooms. People feel cozy in these places and that's they are good retreats. More often though, applying this same kind of informality to a primary residence might make the home feel much more comfortable.

This may have broken me of the desire to build my house with nine or ten foot ceilings throughout. I would likely still put higher ceilings in the entry and great room, but I would probably bring down the ceiling in the bedrooms, the kitchen, and the away room.

Simplify, Simplify, Simplify
From the book: "To be surrounded by an environment that is both beautiful and personally enriching has far more appeal than the futile attempt to "keep up with the Joneses". When we have what the Joneses have, we experience firsthand the inadequacy of the dream. It's so easy for me to want something that someone else wants. It's a normal human impulse, and like most human impulses, it has to be deliberately curtailed.

The Not So Big House accepts the fact that "not so big" is very different depending on who is saying it. They have examples ranging from 800 square feet up to a few thousand. The idea is to put more thought into it rather than just throwing more square footage into the mix.

For me, having an architect-designed house would be be way too expensive to satisfy my cost/utility balance. I am glad I read this, though. It will help me to know better what to look for in existing floorplans as well as know how I can make small tweaks here and there to bring out some features that will make the home more satisfying to live in.

that you do not know be useful or
believe to be beautiful"

Air Conditioning

Let me begin this post by saying that it is for me. It's going to be painfully detailed and of import to nobody but me. You will be bored by technical details of something that doesn't really matter. I suggest you read no further.

On the other hand, if you can't resist an odyssey, then by all means, read on.

The purpose of this post is to chronicle the saga of the air conditioning system in my Land Cruiser. Over the last two years I've been putting money into the system a little at a time. At each step I thought that there was just some little thing to do to get the system back online. Each time I enjoyed AC for a short time, only to have another part of the system fail. So let's get started.

First some basics. Here is a diagram of my AC system. The major components are the compressor, condenser, drier, expansion valve, and evaporator. They are labeled on the diagram. The evaporator and expansion valve are behind the dashboard, everything else is in the engine bay. The refrigerant flows from the compressor to the condenser, through the drier, next the expansion valve, finally the evaporator, and back to the compressor.

Starting in the summer of 2013 I found that the AC wasn't making the air cold. At this point I didn't know jack about automotive AC, so I started the process of troubleshooting and figuring out what I needed to do. Soon I decided I needed to get this thing sorted out because I had to go to Utah in October 2013 to see my family and get some machinery.

The first step was to get it into a shop for some diagnostic. This is done by charging the system with a dye which shows brightly under UV light. It is very effective. The process of charging the system is relatively time consuming and requires special equipment, the two main contributors to expensive repairs.

9/4/13 $232
The first round of diagnostics. This determined that the shaft seal on the compressor was bad. 18 years was all it could take. This required replacement of the compressor. I also learned at this time that when the compressor is replaced you also need to replace the expansion valve and drier. The shop was kind enough to provide an estimate of $1125 for the repairs.

9/5/13 $285
I ordered all the stuff necessary to do this job. The compressor, drier, expansion valve, and other small parts. I was able to get all this stuff replaced on a Saturday, but I still had to take it back to the shop to get it charged and leak checked.

9/19/13 $204
This finished the initial repair. They charged the system and returned it to me. At this point I had saved $636. The system was online and I thought I was in the clear.

That feeling was relatively short lived. My trip to Utah had been cancelled, but the AC would have worked. A couple of months went by and I noticed that the air wasn't blowing cold anymore. As you might imagine, this was disappointing, but now it was winter so I decided not to act.

5/16/14 $42
I had the truck back in the shop for another diagnostic. For as little as they charged me, it seems more like a token charge than anything. Anyway, they found that the pipe between the compressor and the condenser was bad.

5/23/14 $438
I had them do this work because the savings would be relatively small to do it myself. They ended up changing the pipes on both sides of the compressor and recharging the system. Again, I figured I must surely be in the clear.

Again, this feeling was short lived. If you're keeping track, now I'm up to $1201.

And it still doesn't work.

Now we're into the summer of 2014 and this began a long period of procrastination. Fall of 2014 was extremely busy for us. I was busy at work and at home getting ready to go to Japan. Dealing with this was LOW on the priority, but it still bugged me. Of course, then we were in Japan, and it mattered even less.

This past summer in 2015, getting the AC working was a high priority for me. I wanted the functionality back because I hate it when the truck doesn't have full functionality. I figured the system had leaked dry again, and at its last charge it had dye in the system. The only part of the system that hadn't been leak checked was the inaccessible portion inside the dashboard, namely the evaporator and expansion valve. When I had removed the evaporator to replace the expansion valve in the first place, I cleaned a lot of dried leaves and crud off of it. I think this allowed some deterioration of the thing. So I pulled it again and looked it over with a UV light that I had bought. Sure enough it had dye all over it. Time to replace it.

6/18/15 $80
New evaporator core. The swap out is pretty straightforward. It had better be, anyway. This was the third time I took it out. Now the total is $1281.

By this point I was tire of taking my truck to the shop for AC charging. My buddy Ned is good at refrigeration and he has many of the necessary tools as well as a bulk container of R134a. After changing the evaporator I took it to Ned's for a charge.

The charge seemed to be going well. The engine was running nice, all the indicators were good, and we again seemed to be in the clear. Then we turned the engine off and noticed a loud hissing. We thought the joint at the top of the drier was leaking, but we wanted to put eyes on it. You have to take apart the grill and the headlight to get in there. When we got in there we discovered the pipe on the outlet side of the drier was leaking like crazy.

At least this is a good smoking gun. Proof positive that there is a problem and you know exactly what it is.

7/17/15 $154
New AC pipe and drier. Note that this is the second new drier. It was relatively easy to swap out. AC isn't really that hard, the trick is knowing the certain little details that will determine your success or failure. On the day I did this swap, I also borrowed Ned's tools to do the charge myself. There were two little snafus in this section of work. I'll go into those later.

The bottom line is I got the system running that day. The final total is now $1435, but it was working.

A friend at work said that it seems like I'm destined to never have AC in that truck. I sure showed her.

Until this last Thursday. October 15, 2015. I was out doing some errands when the engine suddenly began whining with a shriek I never knew a car could make and still otherwise run fine. It was the AC compressor clutch slipping. I later determined it was slipping because the compressor is seized. Compressors that are designed for gas are done in by compressing liquid. If they were for liquid we would call them pumps.

This is what I think happened. Oil level in the system is a critical attribute. Too little and you will burn up the compressor. Too much and you might seize the compressor. I'm pretty sure I had too much oil in it. The instructions that came with the drier said to put a small amount of carefully measured oil in it prior to assembly. I measured it with a syringe. As I was adding oil, it overflowed well below the specified amount. There was also a discrepancy between the Chilton manual and the pamphlet that came with the drier. I was going with the pamphlet because I figured it must be more accurate than the Chilton. When it overflowed I got confused and didn't know what else to do, so I dumped out about half of what I had added and proceeded with the installation. This was the first snafu. The second was that the system charged much faster than I thought it would. Before I knew it I was about 0.1 pounds over the charge specification. It's a small amount but could be enough.

While it was running during the last three months I noticed the expansion valve was very noisy. I don't know if that had anything to do with it. Maybe excess oil causes the flow dynamics to change which causes extra noise. I may never know.

So here I am. I have a broken AC system that has cost me $1435. If I was to allow myself further down the rabbit hole, the next step would be another $285 for a compressor, expansion valve, and drier. Having acquired the skills to charge it myself I would avoid more shop charges for that work. I hate to spend more on this broken system, but on the other hand, the other system components are now in great shape. By replacing the compressor and drier I would be able to start from a clean slate. I now know how to add the correct amount of refrigerant as well as the correct amount of oil. It's just one tiny step and I'll be back up and running for another 15 years.

It seems like I've heard that line before. Time to tap out.
And I thought the power steering story was expensive.
