I have a 48 M diesel that runs beautifully except that the crankcase gets dilluted with fuel. Has anyone ever run into this and fixed it?
 
Your injection pump is leaking into the crankcase. It has an o ring around the shaft that is bad. You will need to get someone who knows about injection pumps to fix it. DO NOT RUN your tractor with fuel in the oil, it will cause severe damage to the engine.
 
Turn the shutoff under the tank off when you stop the engine, & it should stop the leak when the engine is off. Our 450D has the same problem, but we never have problems with it leaking while running. Should get it fixed.
