Hi guys my 86 GN has sprung a leak. The rear main seal was replaced not long ago and after several inspections the new seal doesn't seem to be the culpret for my leaking problem. The leak seems to be coming from the rear of my oil pan. The gasket is wet and has been squished out by someone over tightening the oil pan bolts. The all around the end of the crank, bell housing and flex plate are dry. No oil slinging and seems to drip while sitting. Which type or brand of gasket would you guys recommend? How hard is the gasket to change. It looks as if I need to lower part of my exhaust and possibly remove a motor mount bolt and raise the engine a little...Is this correct. I sure as hell don't want to raise the engine if I don't have to. Looks like an all day job with basic tools to do it right?
