Default leaky rear main?

just had the motor pullled to change rod bearings, put it all back together with new seals and gaskets. now the clutch is slipping. put it in 6th around 50 and put the pedal to the floor, and it just revs right up. rear main leaking you think? i didnt personally install the rear main, my dad did, but i hear you have to get these lined up perfect or theyre gonna leak. the car only had 30 miles on it whenn it started slipping. im just wanting to hear other opinions before i pull the tranny back out. btw the clutch had plenty of life left when we inspected it.

The rear seal is very easy to mangle during installation. I popped $50 for the J-tool on eBay figuring it was cheaper than a clutch, and it works great. Let us know what you find when you get it opened up.

It's way too easy to screw up the rear main seal. I did that to my ls1 third gen, and in about 15 minutes it's puked out about a quart of oil . I too hope my clutch is okay.

Not necessarily, I've seen LT1s and LS1s with oil soaked clutches and no external signs of leakage.

when i first pulled my clutch when the motor was torn apart, the rear main had been leaking and the clutch was oily, but never once slipped on me.
