I drained the coolant out of my 6 cylinder Ford Lehman engine model 2715e and there appeared to be engine oil in the coolant. Has anyone experienced this problem?

consider a leak in the engine oil heat exchanger.

I will check and pressure test the oil heat exchanger before I consider the head gasket.
Goud luck
