What is the cause of diesel fuel in crankcase oil?
Can you tell me the model or your 6cyl? ie isc, isb ect or an engine serial number? There are many causes. I will help if you can supply some more engine info.
Hi there. Your engine doesn't have injector cups. It is a smaller cummins it is a 359 cu in engine. More than likely you may have fixed and also caused another problem at the same time. If you are getting whits smoke then the possible causes are: coolant in compression chamber, Injection timing, low compression.
Given this information the first thing to do is check your injection timing. If the timing is off a couple of degrees then the fuel is not being burned all the way causing raw fuel to enter your crankcase. If your timing is correct then the thing to do next is to pull your injectors and preform a compression test. Doing this will find the answer to your problem.
