[bill 4.3l 5spd]

ok truck =91 s10 2.5 5spd 2wd 122,000 on it.


monday morning i noticed the truck had NO power what so ever. after opening the air cleaner i seen it was full of oil.
thinking bad rings i did a compression test and it came back good, all even.

any ideas?? i know the timing needs to be tweaked and i think that to be part of the lost power problem, but the oil in the filter i dont know about????

Really? I just picked up an Olds Ciera with the same problem. Just curious though, what are the PSI specs on compression? I checked and checked my Chilton, but can find nothing.
