My L2900DT ( Dual traction) D1503 L-A has a oil leak at the exhaust manifold. I would like your opinion about what would cause this oil leak, and how to fix. After cleaning this is the oil it leaks after 4 hours run time. I did not notice loss of power, and no abnormal smoke.
The tractor is NON TURBO, shows 2200 hours and is most time not worked hard.
I tried to put a picture on this page, but I only managed to have a picture in a attachment.

Most likely not engine oil but unburnt fuel with exhaust carbon coloring. Short runs, not getting the engine up to operating temperature. Tractor needs to be taken out and had the snot worked out of it for several hours. Quit babying it.

Have you knowticed if crankcase level oil going down ? BTW the DT does not stand for dual traction . It means direct transmission , gear tractor .

I haven't been able to post pictures in over a month using TBN icon and still haven't figured the attachment out yet either.
Oil coming out of the exhaust manifold, that is weird.

Thats interesting first time I have heard it refered as dual traction . For years DT is , was known as direct transmission or gear tractor . The reference below contradicts Nelson's article . Anyway I don't want to derail Bert's original question .

Oil must be getting by the piston rings or maybe exhaust valve somehow but if thats the case it should be burning oil and smoking more, crack block and compression would be lost.
