I’ve heard about it happening but haven’t experienced it personally. I’ll be changing mine out as funds allow to prevent it from happening. Once of prevention/pound of cure.

My May of 22 built blew oil all over at 18,000 miles.

Did you use the free oil changes? Those kids working in the oil change bay are training to be a tech. Turns out, they create work for the experienced guys down the road.

If the filter is changed correctly, there's a good chance you will avoid having issues. Correctly isn't really appropriate. When installing the cap, be sure to wipe it clean and lube the new o-ring.

I do not use the torque specifications to secure the filter cap. Just turn until it stops. You can feel it when it bottoms out. Jethro is not your friend who you would want to do your oil change.

Unfortunately, when the Jiffy lubes and dealerships cause the damage, it is really hard for anyone to prove that they did it.

I’ve considered doing my own as it seems it can’t get much easier on a Jeep. Knowing the does and dont’s is the key

I've only seen it once in my circle, and that was actually on a 2014 JK 3.6L.

Heard of it a couple times in the local Jeep clubs.

That's about it.

Replacing the oil cooler appears to be quite complicated, disassembling part of the top of the engine to access it. Shop recommended all aluminum replacement mfg by Doorman. Thanks.

It looks fairly complex, but in practice it really isn't if you are mechanically inclined. I watched a friend of mine do it twice He did a plastic replacement, goofed up a seal, then had to get back to it and since he was doing it twice he bought the Dorman the second time.

Honestly, getting down to it is relatively easy.

Actually removing the oil cooler once you access is harder with all the hoses and sensors attached to it.
