All,
As many of you know I have a 71 350/270 L-48 4 speed. Ever since it was rebuilt 3 years ago I have been chasing oil leak(s). To date, I have fixed the small ones from the distributor, the oil pressure line, and (finally) the valve covers. I still have one that puzzles me, however (at least a little).
My engine continues to have oil on the REAR surface of the oil pan, and on the FRONT surface of the clutch inspection cover. There is NO oil within the clutch or on the inner surface of the inspection cover. It is dry as a bone there. The oil then goes back across the bellhousing, onto the trans, etc thanks to airflow as I drive along.
My question is this: is it the rear of the oil pan gasket that leaks, is it the rear bearing seal that leaks, or might I have a totally different gremlin? I know that to fix either requires removal of the oil pan, but I would like to know what I'm in for before I start. And yes, I actually watched my engine as it was assembled, and I know the rear seal is not in backwards. :)
Thanks for any assistance you can give.
Patrick
