Has anybody noticed a deep gouge where the pan plug hits the pan on my 2012 f150 with 5.0 engine I never over tighten the pan plug. the mark is where the metal around the outer part of the plug hits the pan it looks strange. but the dealer told me it was normal lol lol lol .The pan plug tightens fine and don't leak. It like the part in the pan that is welded was pulled tight against drain plug. Maybe it is normal?? Thanks guys for the help..
