Rear main seal keeps leaking!
I'm at a loss.. I've replaced the rear main seal 4 times now, used a crank repair sleeve to seal off the groove, used OEM seals, and yet it STILL leaks after high rpm, and it leaks bad (dripping) any ideas? I'm tired of ripping off the tranny and I just wanna stop this leak so I can put the turbo on already, compression is good (180 across), leak down is good (5% across), crankcase is ventilated via catch can, I did NOT get the crank polished when engine was rebuilt (totally didnt think about it, was too excited to put my rods and pistons in), other than that everything is brand new, wiseco pistons, h beam rods, supertech springs, arp studs, balance shaft delete, and my oil pressure gauge is pegged at 100 when doing pulls, could my oil pressure be causing the problem? thinking my gauge might be faulty since the psi reads 40psi warm idle then jumps to 80psi at 1200-1500rpms, the crank had a pretty nasty groove worn into where the rear main sat, I'm contemplating on getting a crank kit since i can get it from my work for about 170 but I dont wanna pull the trigger if its not the issue.. anyone have this problem before? looking for some insight
