I recently purchased a 2006 F-250 Lariat, crew cab, 4x4, with a 6.0. It has 68k miles and is what appears to be a very well taken care of, stock (with the exception of an coolant filter kit), 1 owner vehicle. That being said, I noticed that the truck has a small oil leak between the transmission and the back of the oil pan. It leaks/weeps enough to get a drip or two on the bottom of the transmission and oil pan. At first I noticed the drip/leak was from the right side, but upon closer inspection, it appears to be damp around the base of the dipstick tube. Is there anything specific I should be looking at to tighten down before I take this into a diesel mechanic? Attached are some pictures. Thanks in advance.

thats really nothing for a 6.0

but a mechanic will probably run a dye to test for the exact leak location

rear main and bed plates are common

and pricey to fix

It looks like its being pushed from the front to the back just from your fan and driving is their any oil on the front of the motor?

You are correct. I just went out to take a look and this is what I found.

By how its being pushed it looks like your front main seal is leaking not bad tho a little drop of oil being pushed by the fan goes a long ways

Is the front main seal something critical that needs to be addressed asap? I don't want to get stranded, as I do tow a 25' fishing boat that weighs approximately 8500-9000 lbs fully loaded, including the trailer.

In the meantime I will degrease the area and monitor to see how quick she is leaking. Thanks for the input.

Just like anyother seal it could last 10 years or 10 days just keep a close eye on it but the front main is more important on our trucks cause the low psi oil pump is right behind it

it won't likely ever just let go and leave you stranded

it will maybe drip more or maybe just stay the same
