I did my valve adjustment last night and I followed my shop manual, which said to adjust all at .016 while cold. I like working on a cold engine anyway so didn't even think twoce about the .015 for a hot engine.
I took a long hard look at how to turn that little 2.2 and it had me stumped for quit a while but was successful by putting a ratchet on the power stearing pump pully and rotating it while pushing down on the v-belts at the same time. Pushing down on the belts tightens them enough to pinch the crank pully so it will turn. I suppose one could tighten the belts up enough but it is no problem for me to push on the belts. It doesn't take much to rotate the crank anyway. Not like a gas engine.
Hope this helps. I have no idea when the last valve adjustment was done on my engine since just purchasing it so I am in the middle of performing all the initial checks. I found the valves were at about .032 so twice as much as recomended.
Getting 32.5 mpg so far so I am
. Better than the 15 mpg
I get with my 4x4 Dakota.
