TC33D Fuel in Crankcase

[3strucking]

I have a low hours NH TC33D that is leaking a lot of fuel in to the engine oil. Tractor starts and runs fine. There is no lift pump on the 843-N engine. I am guessing that there is a o-ring bad in the pump somewhere. Has anyone else had the same problem?

I have not but if I'm remembering correctly it can occur when something (seal) has failed with the fuel pump. I'll see if I can find an old thread.

This was the only one I could find doing a quick search:

Oil & Fuel - Ford 1715 Injection Pump Info

So I learned from my other thread about fuel mixing with the oil while the tractor isn't running that the seals on my injection pump need to be replaced. I know I need to pull the pump and send/take it (& probably the injectors for good measure) to someone that can overhaul injection pumps...

does it smoke on startup at all? could easily be a injector

Tractor is heading for 20 years old. Send the pump and injectors out and get new o-rings and seals put in the pump and have the injectors tested and rebuilt if needed. The pump is the probable culprit.
