I put an oil catch can on my new 2024 and was amazed how much is already in it after 300 miles! Working at the shop it is sometimes comical to see how much oil will dump out of a 3.6L intake manifold when removed lol

Ok I quickly read it. If your dealership is kicking your warranty due to a oil catch can then you have a shitty dealership point blank. I have been a tech for 15+ years at a dealership and am told to warranty stuff that shouldn't be warranty everyday. A oil catch can is the least of a dealerships worry unless they are just looking for a way out.

Is there a condensed version? I'm not reading 25 pages lol
If I remember correctly: blown engine, replaced under warranty, blown engine, something about no mods to the engine, but clearly modified it by installing a catch can, Stellantis said that the original replacement shouldn't have been covered by warranty, everyone was upset.

Not sure what the outcome was.

That is crazy as a dealership tech lol the service department must have really hated the customer.

Potter, you sound like a great tech working for a great dealership. Unfortunately, there are not many dealers like that out there. The dealers here in Denver look for any reason possible to deny a warranty. My 3.6l blew up at 25k miles. The tech told me that a catch can or even modified intake could have made it difficult. I realize there is the Magnuson-Moss Warranty Act (MMWA) to help the consumer on this, but going up against Stellanis is a big battle that will cost more money that most people have.

I am not sure if it is because the dealers out here are so busy that they don't want to get tied up with big projects or what. I had similar experiences on the East Coast and Midwest. It is not a new problem either. I remember taking my 97 lifted TJ to the dealership I bought it from in Seattle, WA in 1999 because the door was rusting on the inside window frame and actually started to pull away. I was turned away because I had lifted the vehicle. I pushed back as the lift had zero to do with this rust problem, nothing else on the entire Jeep was rusted... Took it to another dealership and they were equally as shitty. Ended up waitng a few months and got a friend with the same color doors to swap them out and put on his non lifted TJ. They repaired the cracks and repainted the doors...

I added a UPR catch can and it completely eliminated my sever spark knock
The down fall on most catch cans mainly the 3.6 is they are to small and can fill quickly when you are at a steep angel.
To solve this problem I added a 4 ft 1/2 drain hose with a ball valve at the end of the hose doubling it capacity.
After over 10k miles using the catch can I have never had oil in the can it self. It was all in the hose keeping the oil out of the PCV system.
When and if I had to take it to the dealer it could be easily removed.
At this point with all my mods they will not warranty any thing on my Jeep. So its all on me.

So what’s the right answer install catch can and remove before dealer visit or leave stock and wait for engine failure and hope warranty covers it? OMG waited over 20 years to get this Rubicon and it’s a ticking time bomb?

A catch can really isn't needed for naturally asperated applications. I'd suggest not bothering with it. A dealer shouldn't give a shit, if they do the tech is lazy and doesn't feel like working on the vehicle. Just find a different dealer if that is ever brought up.

Warranty work pays less, sometimes a lot less than what it really costs to do. With most techs getting paid by "book" time, they would rather fill their time doing things that pay more. If they have a job that book pays $500 for for 2/hrs, but they can do it in an hour, they just doubled their money. Warranty work can state it's 3 hours, and that's all they'll pay, even if it's BS job like pulling the whole F'ing dash to replace the heater core and it takes 8 hours to do it per procedure. Some shitty shops will tell you it's not warranty hoping to get you to bite and pay their full price, then "help you out" by lowering their price since you are stuck, while still filing for warranty work and still making the money.

If you saw the amount of oil that dumps out of a 3.6 intake everyday you might reconsider lol

Yeah... I used to put catch cans on my vehicles... some would collect oil, and I'd have to remember to dump REGULARLY, and some, not so much.... it was like, why did I bother spending the money!?
There's a reason OEM's don't put these things on vehicles... it's called "above & beyond" normal maintenance!
I just don't GAS anymore! ??
There are more important things in life to worry about, than a catch can ?

I agree.
I was extremely skeptical about the use of a catch can put new I had to try something to stop the severe spark knock and had read that it can help.
After the oil catch was installed absolutely NO more spark knock and the oil that it collected was amazing.
I kept it simple by adding a long drain hoes with a ball valve at the end of the hose doubling its capacity and easy to drain.
