Auto Shop Class

So, I didn't really have too much time to get this car stuff done, but the Volvo needed it. Especially since the T5 is now our only automobile. Tuesday I came home and pulled her up on some makeshift ramps and changed the oil. It was not too messy, but while I was under there I noticed that some oil had leaked, and is dripping slowly from the turbocharger. The cause is as yet unnown, as my ramps were not high enough to get all the way under there. I think the oil change went okay, but I inda wreced my thumb when the drain plug finally loosened and my hand slammed into something on the bottom of the car. Well, it wouldn't be working onthe car if you didn't hurt yourself, right?
So, since that Auto Shop 101 project was done, it was time to get started on 102 and maybe 103. Here is what arrived last week from IPD: Spark plug wires, spark plugs, distributor & rotor, torx tool set, brake fluid & brake pads (not pictured).So I removed my bike from the garage and pulled down the workbench to get started.First step was to remove the spark plug cover, which is the black piece on the engine that proudly says "Volvo 20 Valve." I noticed while taking it off that one of the special Torx screws that holds it on is missing, and another is stripped. The rest are corroded, so I'll need at least two, but may as well get all six new. They're $1 each from IPD.
I removed the spark plug cover and was surprised to see oil sitting in the indentations on top of the engine. It looks like oil somehow seeps up out of the oil fill cap, and then trickles under the cover. That is a bit of a relief, since I was a little concerned about the old oil on the back side of the engine, and I'm sure this is where it is coming from, not from a bad gasket.
So I replaced the spark plugs one at a time with Denso Iridium plugs. I'd had Bosch Super plugs, which were copper. I've actually heard conflicting reports. But it sounds like if you are driving a Turbo and really pushing it a lot, Iridium plugs are not as good as copper, since they run hotter and Turbocharged engines generate lots of heat. But they actually do better where you are in a lot of traffic or colder climates where the engine does not achieve as high of temp. Sadly, I don't take many spirited drives in the T5 these days, so I think these plugs will be good.
After changing each plug, I went through and replaced the wires with a higher-quality upgrade. The routing of the wires was a bit of a pain, especially trying to get all of the clips back in place. I did it pretty well, but then lost part of a clip that clamps down on all five wires where they exit the spark plug cover. It sprung out of my hands while I was trying to force it onto a wire, and fell behind the fuel injector rail, and then out of sight.
Here are the new wires installed. I decided not to do the rotor and distributor last night, because I had a lot of other stuff to do and was tired of working on the car!
So what is next? Brake pad replacement and brake fluid flush need to be done, and maybe my dad will be able to help with that while he is in town. Also I need to take the car in to have somebody look at the turbo oil leak and at least tell me what the problem is. I've also started to notice some noise coming from the fuel pump, which is located under the back seat/cargo area. Hopefully that doesn't go out!
Finally, a weather report: Bring clothes for rain/snow/wind if you are coming to Wisconsin on Sunday.

cool man. I used the Iridium plugs in the 900 and they've been great.
