More leaks at the rear of pan??? Did the builder at least run this for awhile to verify leaks etc?
I hate to sound like a broken record but what did they use for the rear oil pan U seal?? Same OEM rubber 3 tab seal... or did you have them do the cork gasket with sealer???
if its leaking in the same spot looking like a rear main... im still saying the rear oil pan seal could be the culprit, it was on mine 2 times and acted just like yours, was never the BOP 1 piece main seal, it was that dang stock 3 tab rubber POS!
Best of luck finding/repairing it... or just live with it like so many pontiac owners do and put down some cardboard.
