Engine/Transmission (1998.5 - 2002) fuel dilution

[MPalachuk]

Just got my oil sample back and have fuel in oil, Who has been through this and what did they find? Cant decide where to start, Injectors or lines or vp44. Lift pump was bad in december and changed. Can that take out the seal? Truck has 105000 and is making a little oil. So what do you think?

I don't see how you injector lines could be at fault. On a 24V it might be possible for an injector to have a leak under the valve cover. The VP44 can definitely have a leaking shaft seal that will do this.

There are probably o-rings around the outside of the injectors. They could be getting bad.
