ck. while running, under the intake in between the valve cover w/ a small flaslight. When the heads leak, more than likely oil will collect in that valley under the intake. There, it will fill then run-off in a weep hole and come out a hole in the bell housing in front of the trans. I had this happen to my 380 prior to tearing it apart. Funny thing though, it ran ok despite the bad head gasket. Could just swap valve-cover gaskets and hope that was the problem too. If is is your head gasket, the leak will eventually become worse. Finally, if you degrease the area aroud the leakage, you may locate where the origin oil is coming from. Hope this helps. Les
