fuel in oil problem?!?!?!
ok guys i recently replaced the head gaskets on my car and put everything the right way and turned on fine..later i found out that oil was leaking from the back of the intake manifold so i took off manifold and cleaned it and resilicond it cuz i hadnt put alot before.. i replaced the intake manifold gaskets and out everything back the way it was again. i had trouble getting the timing right until i finally got it..i noticed that the plugs were soaked with fuel so i changed them. white smoke was coming out of the exhaust like crazy and i checked the oil and it smells like fuel really bad!!..i changed the oil and its still doing that same thing idnt no wat it can be..can some body help me out here?!?!?!!

A leaking injector when the engine is off can dump fuel into the cylinder, which gets past the rings into the oil.

Do a compression check of all cylinders, make sure that they are within 10% of each other. You may have some bad rings letting fuel pass by the rings getting into the oil.

Re: fuel in oil problem?!?!?!
you intake gaskets may not be properly seated allowing fuel to leak past the intake port on the head and directly into the oil galley...
