I forgot to report progress. Fixed! Virtually no leaks! The old pan had a pretty significant split and what appeared to be a JB Weld repair. The first EBay pan was rejected, way too pitted, although it was cool since it was early with fine thread and brass plug. Second one newer, not pitted. Sealed and torqued with a small 3/8 torque wrench. It worked perfectly. Checked screen. Clean inside.I was convinced my rear seal was leaking and it may well be but it was odd that with my car came 2 new oil pan gaskets (higher priced versions). Bolts are not over tightened. Today I discovered why. The pan has a 1” x 10” seam of epoxy in one of the valleys. The defect was painted over. It’s oil moist and the source of my leak. I have a replacement pan coming. What sealer should I use here in USA? Typical I would bond the gasket with Duco or 3M adhesive to the pan but uncertain what to use gasket to block? Lastly worth braising the old pan?
Thanks
