It has become apparent that the oil level is increasing in the oil pan of my Case 336. In some context of discussion, a while back, I read that often the primary fuel pump integrated on this Bosch injection pump is the first suspect in letting fuel into the crankcase. Perhaps if someone is in the know on this I'd appreciate confirmation. Should this be the case, how involved is it to install the seal or seals involved? Is there a seal kit for just the primary pump? Everything else is perfect regarding the fuel system function. I was prepared to take the whole injection pump in to be resealed but if it happens to be the primary pump seal(s) it would save a lot of time and money. Thanks for expert advice.

Can get the kit at a place that services diesel pumps. Couple O-rings and a gasket is about all there is.
