It sounds like to me that it isn't the main seal leaking, it might be the oil pan gasket or maybe even the side seals on the main seal holder leaking when the revs go up shruggy
If it is the side seals or a pan gasket it won't leak oil onto the engine side of the flywheel, it will leak down around and over the edge of the oil pan instead scope
Take your time with car up on jack stands and have someone run the throttle while you look at the oil leak to see if you can make sure EXACTLY where it Is leaking from scope twocents Good luck thumbs
