Oil pan seal at 42,000 miles and 6 years really?

Hi guys wanting to see if I am alone here or if this is common place at my age and mileage. I know they tend to go at millages >100k bit I am only at 42,000. I had the car into a local Indy shop to change the brake fluid because it was closer than the 45 minute drive to the dealer. They told me that there was an oil leak that looks like the oil pan seal.

Is this normal with a car that is so young and with so few miles? The car is still under CPO till April next year but the yearly oil change is due soon and if the gasket is leaking and they are going to drain the oil I want them to change it before the CPO coverage runs out. I have complained about loosing oil before and they said there was no leak, I am thinking now it's just got noticeable.

I just had my Mechatronic sleeve covered under CPO @ 73k miles for $50+tax, seems like it's a common issue that comes up when the temps get colder and you let the car sit for a few days in the drive way.

The spots in my drive way were the clue that it was one of the following:
1) Valve cover Gasket
2) Oil filter housing gasket
3) Mechatronic sleeve

All common issues.

Mechatronic sleeve leak is not at all irregular. A leaking oil pan, main seal, head gasket, etc are not common. Usually in terms of gaskets and seals itís the ones mentioned above.

Make sure they fix it under CPO if it is leaking its a very expensive fix, the entire front end of the car as to be disassmbled to drop the pan.
Gotta pay to play.

First order of business is to verify the source of the leak. From what I can tell your indy didn't pull the plastic undercover pan and is guessing. Mech. sleeve or oil filter housing gasket are the most likely.
I have no confidence in what your indy told you if the pan was not pulled...

Miles and age are both factors for gaskets. The oil pan gasket on these cars tends to seep a small amount but not usually enough to cause an issue. Of course you can see some residue on the engine but normally not enough to worry about. Since it is CPO I would try and get is changed, if it weren't I would suggest that you not worry about it.

Factors are these cars are bad ass performance machines but things wear off especially factory parts as long as they are replaced with quality shit you'll be good. Replace it and you wont have to ever worry about it down the line. Peace of mind
