leaking rear main on new 4.o

i hope some one can shine some light on this for me. I had a new reman engine put in my yj from promar engines. the thing seems to run fine but with just over 3000 miles on it the rear main started leaking. the mechanic is trying to say the motor probably had a bad seal from the factory. After dropping so much money into this thing, I dont want the same guy touching it if its something he messed up. How tough is this to do yourself? any thoughts out there. thanks joe

Since he only installed the motor, he's probably right that the seal was placed in the block poorly by Promar. It's not like would have had access to screw it up on install. Do a google search for this, it's not hard, it's just messy and you need to take your time and use the highest quality seal, not some cheap replacement.
