Have a really clean HD6G (Buda diesel 50's vintage)  Have had it in covered storage forever. Of course, have hardly used it.

Went to start it and on pre-start fluids check found oil way high and thin. Dropped some oil from pan and no coolant. Oil smells like diesel.

Question-What is likely the problem? Any thoughts appreciated. Any ideas on fixes would be appreciated as well.

Thanks

    As many have stated, on mine, it was the seal on the transfer pump. If it leaks, it passes directly into the engine oil line that feeds/exits the injector pump. It's a easy fix. Mine had so much diesel in the oil that I believe I could have poured it back into the fuel tank after I drained it.

SKF 4231 is the seal number. You don't have to open the pump up, just remove it and remove the driven gear.
