Is that a diesel?

[ShadowsPapa]

Took it apart and found a rocker had just barely started to eat the cam. The rocker was on the rear passenger side, I replaced all of the rockers and lifters in the entire engine, the cam had only minor amount of wear. After that, it ran like a champ.

NEVER do that! Never. If there's wear on one, you replace both parts. That's a huge mistake.
I know people do it, some get by, but things wear-in together.
You said "minor amount of wear" - a good cam will not have evidence of any wear.

If there's a problem with that side again, you did it to yourself, sorry.

If the cam is being eaten by the followers, the metal is going through out the engine and could cause a failure else where in the future.

That's not how it works - it's how people believe it works, but it's not reality. Normally all that needs to be done on an engine with trashed cams and followers is a couple of oil changes. There's not shavings going all over shredding other parts. There's a such thing as an OIL FILTER which catches things. And the vane type oil pump isn't like the old gear pumps people are used to which get destroyed by metal bits in the oil. Think of all of those that get repaired - and all the dealer does is a filter and oil change - and nothing else is harmed. Metal bits are washed down to the sump - they don't keep traveling through some channel over to other parts to destroy them.

Again, if it's a failure on the same side, you made a big mistake by not replacing the cam.

If I do run into issues, two phrases come to mind: Lawyer up, and lemon law.

Lemon law won't apply to you. Not a self-repaired issue done incorrectly.
You have to give the dealer (IN MOST STATES) 3 attempts at a repair, and, there must be xx days out of service.
In this case, you made the repair and didn't do it correctly. A second failure is likely on you.
You have to give FCA a chance to fix it correctly.
So until you've give them a chance at fixing it - keeping your hands out of it, lemon law won't work.
If you "lawyer up" like angry people like to say - you'll lose some points on your self-"repair".

I had my JK for 12 years and know what a Pentastar sounds like. The sound coming from the engine is not normal.

No, you don't know what a Pentastar upgrade engine sounds like - you know what they OLD generation sounds like.
JK is a different engine. Yeah, it's a 3.6, but it's a totally different intake valve train, different injectors (yes, those were changed in the upgrade engine as well) and many other changes.
You know what a Gen 1 3.6 in a JK sounds like, but not an upgrade engine in a JL or JT.
Different animals. And yes, there's a whole lot of injector noise with these. A lot.
The valve train is also not quite as quiet.

I'd never do a half-way self repair to get by on an engine under warranty. If I were to do it, I'd do it correctly - cams and followers (and likely lash adjusters "just because" I was in there already anyway). But you open yourself up to other problems with half-way repairs.

Hey Shadow Papa, maybe re-read my original post. I referenced a JK I had in the past. I got away with not replacing the cam on that one, point is I was able to identify the second the tick developed. It ran fine for another 30,000 miles, I traded it in for my current JT which now has 7500 miles on it and sounds like a diesel. No repair has been attempted on this vehicle, it is still well under warranty. I do know what a JT sounds like, and it does not sound like the one I have currently. If the dealership shines me on, I will pay to have them remove the passenger side valve cover and inspect the cam. If the repair takes longer than 30 days (there are rumors it is taking up to 4 months to obtain parts) I will pursue appropriate action. Sorry my original post confused you.

Warranty covers the cost of inspection and repair.

Repair only takes a couple days. Just let them let you keep the vehicle until the parts come in.

Maybe it is my PC audio, but sounds like normal injector tick.

Does it sound like rattling marbles when you slightly bump the throttle off idle?
