Hello!
I'm assuming you have a diesel engine. If so, the following instructions are the easiest way to diagnose the cause of fuel mixing with your oil.
1. First, pull both valve cover gaskets, inspect the fuel lines that are going to the fuel injectors while cranking the engine, see if any are leaking. 2. If there are no leaks present at the lines, remove all eight glow plugs. 3. Unplug both banks of injectors, then crank the engine over. If fuel continues to spray out any holes, suspect that cylinder has a leaking injector. 4. If no fuel is coming out the cylinders or the fuel lines, but the crankcase is getting fuel in it while cranking, there is likely a leak at the high pressure pump,
