Hey Guys, I was on a few months ago with problems with a 350 chevy in a pickup. It was backfiring, no power, hard to crank, after it ran for a while it wouldn't crank at all. Well, over the months, I set the timing correctly, installed a new 1850 holley carb. adjusted the lifters, all the possible problems everyone touched on. one thing made it better, the next made it worse. it has never been right since it was over revved while working on it when I first got it. I even pulled out the pushrods to see if one was bent, nothing seemed to be out of order in a manner of saying. Now I pulled the cam out, looked ok, timing chain and gears looked good. I had a new cam in the box from another project I didn't use, so I put it in this engine. been just working on it little at a time, when I had some extra time, etc. and also installed a highrise manifold i had laying around. I had got a little water in the lifter valley when I did all this, and today changed the oil to put fresh oil in and a bottle of the zinc additive. when I pulled out the drain plug a strong smell of gas was in the oil. and the viscosity was about that of 3 in 1 machine oil, not even probably 5 weight. My question is, How can gas get into the oil like that? this was alot of gas, filled a 2 gal. bucket up 3/4 full. when I change oil it usually fills it to half or there about. Any ideas on this ?? have I got big problems somewhere??? thanks.
