Truck is a 2WD 22R and has 240,000 miles on it, so time for a 30,000
maintenance. Had a mechanic drain/refill the tranny and differential and
repack the front wheel bearings, and he did a complete brake job too.
Today included:
1) new alternator drive belt
2) new plugs
3) new wires
4) new air filter
5) new gas filter
6) new PCV valve
7) new distributer O ring

new rotor
9) new distributer cap
10) reset timing
Have to adjust the valves some other weekend.
Distributer's been leaking oil for over 10 years now, never took it off
before. Pretty easily actually, crank engine over to 0 degrees TDC,
remove one bolt and it pops out. PITA part was replacing the alternator
belt, had to take the skid plate off to loosen the alternator pivot bolt
on the bottom.
Runs like a top now.
