A Tale of Two Projects

This past weekend I spent time digging a giant hole in my front yard looking for a water main break. Fortunately I found the problem on my first hole as there were two likely places the leak could have been. Once I found the problem but before fixing it, my son decided he would try and resolve a problem with his car. In the process he learned that you never start another project until one is complete. As the water was off in the house, he couldn't wash his hands after working on the car until the first problem was completely solved. He also managed to break both his car and my other son's car in the process and so at the end of the afternoon, we went from having one project to three.

My son's problem was actually fairly simple. In the process of replacing the cylinder head on his 1996 Jeep Cherokee, we broke one of the temperature sensors that screws into the the engine. My son wanted to replace it with a new one and so he went to the auto part store. He immediately broke that sensor in the process of trying to put it in. Naturally that was the only one the store had. Fortunately he was able to bring it back, get his money back, find another sensor at a different auto parts store, and break the new sensor. Another trip to the second auto part store and he got another one. Yes, the temperature sensor is incredibly brittle and breaks easily. One would think they would make them a bit more resilient.

The 1996 Jeep Cherokee actually has two engine temperature sensors and the one my son kept breaking is the one that sends information to the temperature gauge on the dashboard. Unfortunately the new one told my son that his engine was overheating and so my son couldn't go out with friends that evening. He was pretty bummed. When we popped the hood and checked the engine, it didn't seem any hotter than normal and didn't have the usual signs of the radiator boiling over. So we needed to determine if the engine was really overheating or if the temperature gauge was bad.

I'm a firm believer in the saying that "A man with one watch knows what time it is, a man with two isn't quite sure." In 1997, the engineers at Jeep decided the second temperature sensor in the Jeep Cherokee was superfluous and removed it. Fortunately for us, our job was to tap into the second sensor on my son's Cherokee and see if it was giving the same high-temperature results. All we needed to do was to tap into the car's OBD-II computer. Fortunately my son has a code reader that is a little more sophisticated than mine and it reads various parameters that include the engine temperature. The only catch is that the car has to throw a check-engine code first. My son tried unplugging various sensors only to have the engine keep running without any problems. He even tried unplugging one of the spark plugs with no luck. Finally he pulled the plug on one of the fuel injectors and the car threw a code immediately. He checked the code and the engine parameters and discovered that the engine was in its optimal operating temperature. That means the gauge sensor was wrong and his car really wasn't overheating. We now know why the engineers at Jeep took out the separate gauge sensor and just use one now.

The weekend is over and the hole in my front yard is now filled in. My son's Jeeps is running fine and the erroneous temperature gauge seems to be fixing itself. My son has also fixed the problem that arose on my other son's car. It took a couple of days, but things seem to be back to normal. At least until the next weekend.

Satisfaction of a Job Well Done

This past weekend I spent 15 hours working with my sons to rebuild the top half of an engine. The 1996 Jeep Cherokee that my oldest son drives was misfiring in one of the cylinders. We worked on all of the possible causes and determined one of the valves was bad on the 3rd cylinder. I could have paid $800 for a valve job as I don't know how to do that. Instead I just purchased a new cylinder head for $300 and replaced it with my boys.

We started working on the engine Friday night. We were not sure how easy the exhaust manifold bolts would be to remove and we wanted them to soak in PB Blaster overnight. We drained the radiator, removed the power steering pump, and sprayed the bolts. The next morning my son removed the air compressor for the air conditioning system without disconnecting the refrigerant hoses. By then we had enough stuff removed from the engine we could remove the valve cover and head. Sure it took a bit longer than a certified mechanic but after putting everything back together, the engine started right up. We were all very happy and there was much rejoicing.

The next morning my oldest son posted pictures of our handiwork on his Facebook page. It was a huge accomplishment for all of us and we felt like we were ready to tackle more complex automotive projects. The whole experience made me realize that experiencing success is a vital part of the human existence. More importantly, it is up to us to create our own successes. Should you be looking for your own success, my advice is to avoid computers. Most people think I am bald because of my kids. Nope, it is because I work with computers.

The Right Tool

This morning I took my son to Snowbird and we arrived at 6:45 am. He is on the ski team and has early morning training all of this week and the next. That means he gets to race down the mountain 2 hours before the general public is even allowed to load the lifts. In the past I have just gone to sleep in the car. One of my Christmas gifts was a set of climbing skins to go with my super fat powder skis that also have backcountry bindings. So instead of sleeping in the car, I got out of the car and hiked up the mountain. It has been difficult hiking in the past because I have had to carry my skis and hike in my hard-plastic ski boots. Having the right equipment makes things so much easier.

As I have had a lot of time off because of the Christmas break, I have also been working with my oldest son to fix his car. He is driving a 1996 Jeep Cherokee that keeps misfiring. This problem was occurring when we purchased the vehicle and the dealership that sold it to us was trying to narrow down the problem before we took over. They replaced the spark plugs and distributor cap. They also gave us a fuel filter that we had to install. We also replaced the fuel injectors thanks to a local salvage yard. While things keep getting better, we are still not solving the problem completely. I have narrowed it down to 2 possible problems: The fuel pump or a broken valve spring. Unfortunately I don't have the tools to figure out either one. So this afternoon, I will head to my local auto parts store and borrow a fuel pressure gauge and a compression test gauge. Both are necessary to further diagnose the problem. Having the right tool is very important for me to finish this job.

Computers, tablet computers, and smart phones are another area where it is important to have the right tool. While you can edit an electronic photo with a paint program, it is significantly easier with a photo editing program like Adobe's Photoshop or the open source program GIMP. So if you find yourself taking a lot of time to do something on your computer, tablet, or phone, you might not be using the right tool. Chances are, there's an app for that.

Form vs Function

I was driving in Utah this weekend and pulled up next to a beautiful black Ferrari. I have always wanted one and so it surprised my wife when I told her I would rather have my buddy's tricked-out Jeep (see the picture below). "Why?" was all she could ask once she recomposed herself. I explained that it all boils down to functionality. While I like the idea of owning a fast Italian sports car, it really isn't all that practical for the things I am doing in my life right now. I am happily married and so I don't need an expensive car to help beautiful young women see past my bald head and chubby belly. The speed limit is easily reached in even the most basic car. Yet a vehicle capable of operating in the worst travel conditions comes in handy when you spend as much time in the mountains as I do. Yep, right now I would take the Jeep.

What does this have to do with computers? Well I recently had a conversation with one of my coworkers who is in the process of upgrading one of his computers. He is really into music and so he purchased some expensive sound equipment. No, he didn't just get a high-end sound card, he picked up top-of-the-line studio speakers, mixing equipment and stuff that most normal people would never use, let alone be able to afford. While we were talking, I realized that it would be fun to do the same thing to my computer, but I don't need it. That made me think about how I really use my computer.

To be completely honest, I hardly ever really use my desktop computer. Instead, I use it to connect to other computers that are much more powerful and do the real processing on them. That means I need a fast network connection, which I already have. I also have a lot of windows open into these other servers and so it is nice to have a lot of screen real-estate. That means I need a graphics card capable of displaying to multiple large monitors. That graphics card requires a lot of memory to run well. So while my coworker built his computer for audio, I should concentrate on video.

A Ferrari is a beautiful car that most people would love to own. There are a lot of computers out there that are similar. They are really fast and look amazing. However it is important to look at your needs before buying one. If you are doing a lot of number crunching and need to be "seen" with the latest and greatest, I encourage you to get one. Otherwise if you are like me or my coworker, you might be better suited with a Jeep-like computer that is specialized for specific tasks.

Now that I think about it, I actually have both . . . computers that is. I am typing this blog tonight on my high-end Mac laptop (the Ferrari) while I also have the really fast computer with multiple large-screen monitors in my home office (the Jeep). Now I just wish I could afford both cars.
