I’m at what little I have of my wits’ end. I have a 1964 Chevy 327 in my 57 NAPCO truck. The engine has about 200 miles on a rebuild. It runs well, but I have a leak that appears to be coming from the rear main seal area. I replaced the standard 2 piece seal with an offset type from FelPro, and I have the same leak. I used tracer dye and I don’t see any other evidence of leaking other than around the engine side of the flywheel. The crank was ground .020” if that is a clue. My PCV system passed the pinch test on the hose and nothing’s blowing out of the oil fill tube.
Thanks for any ideas.
Larry
