Ok so I was getting all excited as things are getting nearer to completion. Two winters ago I rebuilt the motor (out of an 87 Fox GT). All new seals, bearings in the motor and I was pretty careful to check and torque everything properly. Heads are new aluminum ProComp.
Fired up the engine and it sounds really great with a fairly big cam in it (Comp 281HR, 512 lift, 220 duration). After running for awhile and a few tweaks of the throttle to rev it up I notice oil after shutdown. Coming off the bottom of the trans spacer plate and the oil pan. So I'm thinking is there some possible way I did not put the one piece rear main seal in right. I don't think so but there it is, something is leaking.
Do any of you think this could be a case of crankcase pressure being too high and blowing oil past rear main? Engine had everything new except I reused the forged pistons and the block did not need to be bored, just honed/crosshatched which was done by a machine shop.
I really don't want to have to break apart exhaust, pull drive shaft, tranny etc to replace a rear main seal but I'm thinking that may be the case.
Any thoughts?
