Diesel in crankcase

dmat58 · Apr 24, 2014

I just picked up a David Brown/Case 885 (it was given to me to get it out of the way)and upon checking oil level in crankcase it was almost to the point of running out. This tractor has been sitting under a shed and has not been cranked since it was was driven into the shed. We pushed it onto trailer to bring home. I checked the fuel tank and it has less than 1/2 inch of fuel in the tank. What do I need to check to find out what has caused the diesel to leak into the crankcase? I read a lot of previous posts and basically don"t know where to start diagnosing the cause of all this diesel in the crankcase. Can anyone help? Thanks in advance for your help.

Generally this comes through the injection pump into the crankcase.

(quoted from post at 02:00:40 04/25/14) Generally this comes through the injection pump into the crankcase.

On DBs, generally it is the diaphragm in the lift pump($40-50). Not saying the bottom seal couldn't go out of the injector pump, but I have never had one. CAV DPA pumps are pretty tough.
