Another example of an oil cooler housing leak

My last oil change, I noticed my JK was down about 1/2 qt of oil and saw no leaks under it. I followed the forum suggestions and looked in the valley right under my oil filter housing and noticed some oil. I dabbed it up and drove a few days keeping a close eye on it and sure enough more oil puddled there. Called my dealer and they said bring it in. You might guess, they said it was a small leak and confirmed that the oil housing case was slightly cracked at this point, but the issue is only known to get worse. They used their last part this past Saturday and will have one end of this week for me. Taking it back in this week to get it changed and Chrysler will cover it under the power train warranty. However, when will Chrysler recognize this is a seriously bad issue that I keep seeing posted more and more often on the forums. The dealers clearly know it is a common issue. I asked the dealer if the part has had a re-design and they said no, they are using the exact same part, but if you use the mopar oil filter NOT an aftermarket you will not experience this issue....that is what they were allegedly told by Chrysler. Can this really be the fix or is this a weak excuse by Chrysler to avoid solving the real problem, redesigning the oil housing case so it does NOT leak!?

Yep This is a problem. I suspect the oil filter is not the issue. I hear very little info on this other than it is happening. Why? That 3.6 is in a lot of cars, not just Jeep. Do they have any reason for the cause of the failure? I have no warranty, if mine fails will they warranty it?

One thing I have noticed, I put the EVIC to read oil PSI and when cold it is really high, like close to 100 PSI. That PSI could make seals fail.

Let us know how the repair goes and ask to see the crack in the failed part. Do they all crack in the same place and why?

Who cares. It is so easy to change, even a caveman can do it.

It is time you stop these repeated fearmongering comments across all threads.

And YES, other cars too have all kind of crazy, o-ring related leaks. A good example is an identical issue of many recent Mercedes engines with oil coolers mounted at the same spot as on our Wrangler. Except that it is a good days work to replace it on those engines.

So it is best to stop mocking the Pentastar1 engine. Yes it is a complex engine if you compare it to much older engine designs, but among all of today's engines it is STILL THE simplest design.

Nonsense. Think about your AC lines.

What Razer said. I just had this happen and I only use the dealer for oil changes because of this issue. I did not want to hear " who ever changed your oil is responsible". Also, when ours went, it wasn't a few drops to give me notice, but a waterfall of oil. Had I been on the road instead of warming the engine in our driveway, the motor would have been toast.

No, this is just an ignorant dealer trying to sell you parts.
The oil filter brand does not have anything to do with the issue of cracked cooler housings.

I just replaced mine on my 2012 and it was not cracked. The O-rings were pancaked causing oil and coolant to seep out. It is not too difficult to do but the oil cooler is $200 as well as the intake gaskets and sparkplugs I did as well so that kinda sucked

After seeing the design of the part and the way the thing seals with the flattened O rings this is what I suspected is happening. Even the temp at time of assembly could make a difference. Hot temps would allow the rubber seals to compress more for a longer lasting seal.

If you did it yourself, did the attachment bolts feel to proper torque on removal?
