I took my 2014 F350 into the dealer for an oil change recently. They ended up having to rush the oil change though because they squeezed too many appointments in one day. After about 500 miles, I've noticed a leak on my oil pan. Looks like upper pan seal too.. I checked my oil level and they slightly overfilled the oil above the max line.
Is the level shown in the picture something that could have caused the oil pan leak? I'm not sure how overfilled it would need to be to cause oil leaks.
I'm on a road trip right now. Should I take some oil out before I drive home? Am I at risk of doing more damage if I leave it for another 300 miles of driving home? I'm just concerned if I drain a bit now, the dealer will say they didn't overfill.
On my 2017 the oil is full below the full mark. The manual says to fill with 13 quarts (with new filter) and disregard the full mark on the dipstick. I say all this to ask, are you sure your full mark is accurate? If my oil indicated that high it would be grossly overfilled.
However, I doubt that is what is causing your leak. The risk of overfilling the oil is that it will foam excessively and actually result in under lubrication. Excessive crankcase pressure is more likely the cause of oil leaking past the gasket. When's the last time you checked your CVV filter?

I just got this truck last year and didn't even know to check the CCV filter.. now I'll check it before I head home. Can it be cleaned or only replaced? Dealer should be open tomorrow nearby that I can get a replacement if needed.
So I'm basically looking at an expensive oil pan seal now?
Edit: Looking into it more and it looks like my 2014 won't have the filter element CCV. Just an assembly that doesn't have a filter element but more of a catch can style. So nothing should be restricting airflow.. right?
You are correct, the non serviceable CCV should not be a problem.
With the engine running is there enough pressure to pop the oil fill cap off when you unlock it?
Just thinking, if the seal was bad but there wasn’t enough oil in the pan to submerge that seal a leak might not ever show up, but if the oil level was suddenly higher than the gasket, and it was defective, I suppose it’s possible it could seep out. But since I really have no idea where the proper oil level is in relation to that gasket I’m really just grasping at straws.
First step, check for excessive crankcase pressure.
Second, lower oil to proper level.
Third, clean exterior of oil pan then observe for leakage.
There are problems with 2012 and up oil pans due to the stop use of the rubber oring on 2011’s which moved ford to cost saving silicone sealant and the version of the sealant and prep process was inferior to the supplies and processes used during the early 2000’s on 7.3’s.
end result, the small cost savings was lost due to the kaxillions in warranty oil pan reseals that needed to be done.
on a properly sealed pan…oil over fill won’t cuase an oil leak…but if your pans seals were inferior..the oil over fill just exposed that.
if you need a pan reseal..best bet would be to have the installer obtain a 2012 oil upper oil pan and use that since it has the oring.
CCV’s and such if clogged just exposed pan seals that are not properly done.
If you want to stop the overfilling problem on the 6.7s you need to change your own oil. Some Ford dealers have been putting in 15 quarts since the 6.7s came out. The dealer software called for 15 for a couple of years and then the owners manual was wrong a few years ago. Do it yourself if you want to know how much of what product is going in, or stand there during the whole process.
I could be looking at this wrong, but that level on the dipstick doesn't look bad to me. Really only you know where the level usually is on the dipstick. If it is overfilled, it isn't much and not what I would say caused any seal leaks.
It is not common for the upper pans to leak at the rear like that. It is almost always in one of the front corners of the pan. I have seen 1 or 2 that were right above the oil filter housing. I would clean the residue off the engine and keep an eye on it. If it comes out of the bell housing as it appears it has been I would be more suspicious of the rear main seal.

Because it is normal to add some oil
between oil changes, check your engine oil
level each time you stop for fuel. To check
the engine oil level consistently and
accurately, the following procedure is
recommended:
1. Have engine at normal operating
temperature (at least into the NORMAL
range on the engine coolant
temperature gauge).
2. Park the vehicle on a level surface, then
turn off the engine and open the hood.
3. Allow at least 20 minutes after engine
shutdown to ensure that the oil
contained in the upper parts of the
engine has returned to the oil pan.
4. Protecting yourself from engine heat,
pull out the dipstick, wipe it clean and
reinsert fully.
5. Read oil level on both sides of dipstick
and use highest level (reading) for the
actual engine oil level.
6. Maintain the oil level within the
crosshatch area on the dipstick by
adding oil as required. Do not overfill
the oil past the maximum line as
depicted by the arrow.

x2.. just looked at my manual.
Son of a gun, I've had the same readings (similiar) before and thought I was over filled as well... I have the bypass on and the spin on filter is huge. So I added about 14 quarts. Then I've drained a little out before... I'll have to pay closer attention this upcoming oil change.
