I was changing oil and put my finger in the drain hole to feel for dirt etc and felt something move. Put back in again and the screen and tube dropped off. Pulled the pan and welded it back. Had 45 lbs of oil pressure as I pulled into change the oil. That was a luck find. G.M.
Hi GM, looks like that exh pipe is inside the pan, must be to heat the oil on a cold day. LOL Walt
