LB7: Fuel in crankcase

[diesel53]

Truck had stock injectors but it could also be a return line couldn't it? Anyway to tell aside from breaking into the valve covers? If an injector case cracks will the balance rate still be normal if functioning correctly?

Any help appreciated

Lb7. It's more then likely a injector issue.

Agreed but I've heard of this issue a lot. Just wondering where the distinction between the two causes is made.
