Serious 904 oil pan leak help

I'm sorry, you practice what you preach I only suggested a way for the OP to stop his " leaking pan" when you jumped in and told him it was a bad idea.
See I'm new to this game I have only been wrenching on cars, trucks and industrial engines for over four decades, retired from a little outfit call Cummins Engine Company.

No wonder you dig cast stuff. LMAO
