Diesel Fuel in the OIL

Diesel Fuel in the OIL. We have had this chat before. I have learned a lot since. Most all agree it is a problem with the injector pump. Engine is a Cummins 8.3 - 1995, with 97,000 miles. Pump is Bosch 392.2425 RX (Recon) Has anyone had actual first hand experience with this?

Have you checked the lift pump? It is above the starter. It's not an expensive item, and it can be a cause of fuel leaking into the engine oil.

fuel injectors

A bad fuel injector will dump raw fuel into the oil. Usually it will be noticed as a miss in the engine much as a bad spark plug in a gasser. If this is the case don`t drive it as the oil becomes diluted and will burn up everything.
