Hello All, I need some help. I have a small oil leak from the back of the engine, running down the inspection plate on my 66. It looks like its coming from behind the pan.The problem is that I've replaced the oil pan gasket twice, then finally with the 1-piece oil pan gasket. Still leaking. I had the oil leak before I rebuilt the engine and I replaced the rear main seal. Still leaking. I'm running out of ideas guys. Please help.

 

Could be the rear main, or the back of the intake.

 

Well, The leak was not there with the stock oil pan, I installed a milodon 8 qrt. pan and then it started leaking. Has anybody had any problems with that pan? I don't think it's the gasket or rear main. I wonder if the pan is just not sealing well enough.

 

Might be bent some. Have you checked the bolts to make sure they're still tight? If I remeber right, fox body mustangs come with a metal plate thatbolts along the oil pan rail. You might look for one of those and some longer bolts. It distributes the pressure from the bolts more evenly.
