Case 1835b - running real bad - diesel in the oil

[ikeeickholdt]

Hey folks, this seems like a bad one but I need a read on what I am getting myself into. First off, I bought the unit from my older brother for $5,000. The unit was already well used. I use the unit on my 3 acre property and have been moving a lot of earth. Yesterday I used the unit all day and the temp light came on. I shut her down immediately and waited for a few hours. I checked the oil and the oil was not on the stick at all. I noticed an oil leak in the rear radiator. I added two quarts of oil. She ran fine for another six hours or so. I checked the oil again and the oil had been spitting out of the dip stick hole. I checked the oil again and the level was way up the stick. I put a hose in and drained some of the oil out and it tasted like diesel fuel and was thinner. The unit will start but runs like it is at low idle. Any foresight would be appreciated - thanks

It could be two things, the lift pump could be leaking allowing oil into the engine, also the injector pump if it is the inline style could be leaking into the engine too.
