Over a month ago my car hydroplaned and hit a median and has been in the shop since. Before i had had a rear main that leaked. The whole time it has been in the shop it has been on jackstands in the front only. My question is, since the oil is up against a leaking rear seal is all of the oil leaking into my bellhousing and all over the flywheel and clutch? if sou will i need to replace my clutch or can i just clean it and put it back in. Please feel free to respond. Thanks.
