841 D making oil

[ed1]

I am in the process of getting my 841 D going and planing to put new sheet metal on it. It is making oil and I understand it could be coming
from the leak off line or the seal under the injector pump. Any input would be appreciated.

Thanks,

Could also be a loose connection to an injector under the valve cover...had that happen on a 961-D several years ago.

You are correct about the leak-off line as well as the umbrella seal. I have had both.
