I have fuel getting into the crankcase when parked downhill. Not when it is running. The injection pump seal has been replaced. And the transfer pump is electric. Has anyone had this problem? It will leak up to 2 quarts over night into the oil. 2000 2wd 2500.

 

Sometimes a seal won't leak while it is turning but will leak while it isn't. Are you sure your pump isn't doing this while it is setting still?

Fuel in oil in a 24 valve is almost always a leaky injector.

The customer finally brought it in. I put 4 PSI to the fuel tank and #3 injector bubbled at the seal with valve cover off. I change all the seals in all 6 injectors. Problem solved.
