The truck leaks motor oil bad when parked uphill. parked on flatland leak is non to slight. appears to be coming from backside of motor
going to check it out in the A.M. Anyone else had this happen before?
Reach in back of the engine, from the top, next to the Distributor. You're looking for the intake manifold gasket to be sticking out from between the manifold and block. (That's why I'm going ahead and doing the 4.3 Throttle body swap. I figure that while I've got the manifold off, I might as well do the machine work on the manifold...)
Anyway, that's where mine's leaking, after 254,000 miles....
