1999 E7 460. I have lots of fuel in the oil. This problem only started after we replaced the heads and rebuilt the jakes.
My mechanic did say that he found a couple of the head bolts around the #4 cylinder on the eup side to have pipe dope on them when he removed them. I have always had a slight oil leak around the back side of #4 eup.
Is this typical or do I have a bigger problem like a cracked block? Any advice would be greatly appreciated.

Fuel travels through the heads as a return. There are 2 plugs on the top ends of each head. That's the gallery.. the EUP's are fed and returned through the block and sealed by 2 orings.. those galleries, run horizontally. If you look behind the #6 EUP on the back of the block, there are 2 1/4" pipe plugs.. they run all the way to the front. In front one is visible behind the over board breather, the lower one is hidden behind the timing cover.. I have found that one leaking fuel. I always re-seal those 2 front plugs when I do a rebuild. The fuel may be passing by the EUP o-rings. Check fuel pressure. 65-80 is good. Near 100 PSI is a bit high and can cause a leak. Are you sure the head bolts are doped and not the lower exhaust manifold studs. They leak oil and need to be doped.. jojo
