Where is the oil going?

[flyingace]

I have a Ford 3000 Diesel and it's using oil - fast. I don't think it's going out the exhaust pipe. I just don't see very much white smoke coming out. The motor seems to run well and starts easily. Minimum smoke at startup too.
I see no obvious leaks of engine oil and the oil itself is clean.

Where can the stuff be going?

Watch the oil level closely in your rear end.
Could be getting in to the hyd system through the hydraulic pump.

UD,
I think you nailed it. I just added 2 1/2 qts to my engine oil and drained 2 1/2 extra qts from the diff housing. At least the engine itself isn't burning the oil, which is good news.

I know there is a main oil seal between the engine oil side and the hydraulic side of the pump. I'm guessing this is the main source of the leak. Is there anything else I need to inspect/replace to slow this flood down?

Thanks a lot.
John.
