I performed most parts of a good tune-up on my car this weekend. My kids are 9 and 11, and I taught them how to change an air filter and do a oil/filter change. My son did the air filter by himself, and they actually worked together to do the oil/filter change. I only had to get the oil pan bolt started and they did the rest. It took about an hour longer than normal, but they need to learn how to do these things. It’s one of my 3 rules on what kids should be able to do when they leave the house… 1) cook, 2) change the oil in their car, and 3) properly handle a gun
I spent a lot of my time trying to get the fuel filter off the car, which didn’t succeed because the steel line is rusted to the filter. It’s soaking in some liquid wrench, so hopefully with a few more applications over the next week, it will come loose. I also changed the plugs and wires on a GM 3100 engine…. the front 3 take about 20-30 minutes to change… the rear 3, not so much. I probably spent the good part of 3 hours working on the back three plugs and wires. The one under the alternator isn’t too bad, probably 20-30 minutes to do. The one on the drivers side rear was the next best at about 45 minutes. The remaining time was spent on cylinder #3 in them middle… between wiring harnesses, sensors and the fact you have to do it all by feel, it took some time getting things lined up.
I’m bruised, cut, scraped and sore, but it’s over. Those 100,000 miles OEM plugs lasted 126,000 miles, so I can’t complain. But I think I did find the source of the rough idle I’ve had for years that the dealer could never find. None of the original plugs I pulled out had the same gap size. They’re supposed to .060, but some were as far out as .075. I also found a small vacuum hose that was disconnected on the rear of the block. That’s back on as well.
I think the only thing left to do is replace the front brake pads. I put semi-metallic pads on last time, and I’m regretting it due to all the brake dust they generate. I’ll replace them with some ceramics and clean the rims. Then the car will still look reasonably good for being 15 years old.
I just wish the body would last as long as this engine will.
