Going to look at an OC 4 diesel that has fuel leaking into the oil pan. I am thinking it is the injector pump that is leaking. Did these have a fuel pump??

DGH, there is one way diesel fuel gets into that motor, by the failed shaft seals on that rossa master fuel pump. If it is the same as the ones I have done, there are two "umbrella" shaped rubber seals fairly simple to replace. The most time is spent removing all the lines so you can pull the pump. Get the model from the pump and talk to a diesel shop, see if they can get you the seals, then ask to borrow the little "hot dog tong tool" that aids in installation. I learned the hard way those seals will tear and they go in facing different ways from each other.

You did not say if it is a Cleveland or Charles City built tractor. I have a parts book for the Cleveland models and it does not show a fuel pump.
