Exclamation Oil leak behind oil pan

Changed the oil today - there appears to be a slow oil leak behind the oil pan. It seems to be comming down from between the engine and the transmission. It's a slow leak at this point, not really dripping to the ground yet I'm going to degrease and clean tomorrow, then run the truck for a few days to see if I can figure out where it's coming from. Any suggestions on what to look for?

Take a look in the valley of the engine to see if there is oil there. Sometimes the oil galley plugs begin to leak. The oil goes into the valley of the engine, then works it way to the rear and down the backside.

I would agree and certainly check and see if the Valley of engine has any oil. At this pint you want to wash the engine really good so you can isolate the source.

This is a list of some that I have seen oil leaks:
HPOP O-Rings
Turbo Pedestal O-Rings
Oil galley plugs

I also personally experienced leak from the oil dip stick seal on the pan.

Thanks guys - I'm on it after dinner tomorrow. Still have about 3k left on my 100k warrenty, so maybe Mr. Ford will pay for it (after the first $100).

check the turbo pedestal and also check the little yellow drain plug lever on the side of your fuel filter. I had the same problem with the little oil drops and it turned out to be the o-rings on the lever were leaking. 50 dollar fix.

Two #90 orings which measure 1/2" O.D. x 1/4" I.D. (1/8" material thickness) will fix the leak on the lever. No need to pay Ford for a complete drain lever and O-rings.

I have pretty much most of the O-rings you need in stock. Just let me know which ones, maybe causing the problem:

ICP
High Pressure Line
HPOP
Fuel Drain
Turbo Pedestal (2 different sizes)

I would start at the top of the engine and check turbo pedestial and then between block and heads. If its all ok there it could be your rear main.
