L245DT engine problem

[billcrapser]

I have a 1977 L245DT (2500 hours). A couple of years ago it started to get fuel into the oil. I took it in to our local dealer and they replaced the injection pump, the injectors, and put new bearings in the engine. It ran great for about a year, but now I am back to fuel in the oil, coupled with no power. As soon as the engine comes under a load, even backing up a steep slope, the engine loses power. it doesn't appear to be smoking amnormally and both the air filter and fuel filter are new.

Any ideas?

I am betting your lift pump has failed and is both not pumping fuel and leaking into the crankcase.
