I decided to install some of them today, along with a few other parts I recently purchased.
I had to remove my camshaft to replace some oil seals allowing engine oil to soak into my spark plug wires. I tried to take lots of pictures, but my camera was acting weird, and it only saved one 'before' and one 'after' picture, along with the one shown above.
So if you just saw the pics, they say "oh look, new spark plug wires". Rats. I worked on this car for 7 hours today. Here is the list of parts I installed:
Camshaft holder o-rings
Timing belt & tensioner bearing
Spark plug wires
Valve cover gasket, tube seals & grommets
All 3 drive & accessory belts
also I adjusted the valves and set the ignition timing.
Except for the camshaft holder o-rings and plug wires, I replaced all those parts 70K miles ago in August of 2006 when my mother still owned the car. If I had thought about those o-rings at the time, i could have put this off another year or two, but oh well.
Still in the 2009 box are one inner and one outer tie rod end. I forget which side they go on, but my tires know. They are showing inner edge wear because of my procrastination. It's not like i bought the best Michelin tires I could find though... oh wait. Damn.
just under 240,000 miles so far on the original engine and transmission. YAY!
