I would say that either you need to put a set of rings in it. When th oil warms up, it allows to lets a lot more oil slip by. If you do tear it down, I wold have it bored .045 over to teak out the ring ridge. M&W make oversized pistons and rings.

That oil is likely raw diesel mixed with soot. When we purchased our 70D back, she slobbered "oil" out the exhaust. On tear down we found one injector dribbling instead of spraying fuel. That bore was worn more than the other & the top compression ring was broken. Is the engine running at 180 to 195F? What does the engine actually put out on the dyno & the exhaust colour?

Ed when is the last time you really worked that R? All diesels with some hours will do that with to much idleing around and never getting warmed up good. Is the oil dilluted, and what weight oil you using?
My sugestion is find some way to work that baby as mine will do the same thing after to much playing around. Should be around a Detroit after it idles all nite. The Baker Fan I got takes it right out of that habit
