My 04 Chevy express 2500 smallv8. Has rear engine oil leak maybe the rear seal. Prior under warranty had 4 flex plates changed also a rebuilt tranny under warranty. I just had new plugs and valve gaskets replaced. I thought it was valve cover gaskets nope. It's clear engine oil leak at rear or engine,. Any info would help. Thank you .jz
