I can relate about oil dripping from crankshaft. I to replaced 2 seals before realizing the crank shaft was worn and a little pitted.I took engine out and removed the crankshaft and had it re-done. Was going to put a new crankshaft in that I found at CARS LLC. in New Jersey but I wanted to use my original one since it was already in my car and broken in kind of. End of the day the crank is back in and I have no more oil leaks ! finally ! but if anyone out there needs a crank shaft you can find them on eBay. Some rebuilt one's or new one's.
