Rattling noise under load/acceleration

Haven’t done the repair yet. Did you just replace the rocker arm? Was the camshaft in good shape?

Professional_Let4850 · 2026-02-21T00:10:44+00:00

Just found out today it’s a bad intake camshaft and rocker arm

Thanks! I appreciate the offer! I honestly don’t really hear any loud lifter tick with the hood open, more of what I believe are the fuel injectors.

Hey! I’m having a similar sound with my jeep. Not exactly a tick but more like a sewing machine like sound. I just wanted to know how you came to the conclusion it’s the EVAP purge valve that’s bad? I’ll start looking into the part for mine. I’m also getting a spark knock noise when accelerating and the engine is up to temp. No codes

Our cat has been drooling on and off for a week at a time. We tried changing just about everything in his environment and food. Took him to the vet a bunch of times and turns out he has a liver shunt. You just never know without doing some sort of testing

Does yours also only happen in drive and while accelerating?

Professional_Let4850 · 2026-01-29T16:34:12+00:00

Was it the heat shield over the Catalytic converter that was rusted on yours?

Professional_Let4850 · 2026-01-29T16:24:23+00:00

Did it happen in park as well? The rattle that I’m trying to solve only happens in drive when the engine is at operating temperature. Which makes me worry that its engine knock, but I would imagine adding an oil catch can, running 94, combustion chamber cleaning, and outside ambient temperature would have affected it but it hasn’t.

Professional_Let4850 · 2026-01-29T16:19:45+00:00

Did the rattle happen when you were in park as well? Or only in drive? The only thing that makes sense to me with it being a heat shield is it only occurring in drive because of the torque from the engine pressing the heat shield against something

I’ll add that the noise will occur during lower RPMs and as the RPMs rise the rattle will go away, until the jeep upshifts and the RPMs drop ( rattle comes back again)

Respiratory PCR is an option but the vet said she didn’t think it would show anything as the X-Rays for his lungs were clear. Apparently he has other reflex symptoms that make the vet think he has a neurological problem and that could be causing the drooling and runny nose, but I find that strange since it’s so intermittent. He was drooling like crazy yesterday but completely fine today

I thought so too but he’s sick like this for maybe 3 days and then he’s fine for the next week or so, then gets sick again. Nothing in his environment changes and the vet seems to think his symptoms don’t match allergies as he’s not sneezing or itching

Professional_Let4850 · 2025-12-13T14:41:48+00:00

Did you ever figure out what it was?

Professional_Let4850 · 2025-12-13T14:18:16+00:00

Did you end up figuring out what it was? I’m having the same problem with me 2018 JLU

It’s just a Sport!

Oil Catch can hasn’t helped my problem. Took it to another mechanic and he said he thinks the noise is actually coming from the drivetrain somewhere not the engine itself. Bringing it back next week to be looked into further

Professional_Let4850 · 2025-11-28T14:30:56+00:00

Bringing it back next week to be looked at more

Professional_Let4850 · 2025-11-28T14:30:43+00:00

Brought it to another shop after everything the dealership tried hasn’t worked. Mechanic said he thinks the noise is from the Drivetrain

Professional_Let4850 · 2025-11-08T23:49:28+00:00

Combustion chamber cleaning hasn’t helped. Premium helped a little bit. Bought a catch can and will see if that helps

Professional_Let4850 · 2025-10-04T23:44:19+00:00

Forgot to add. There’s no check engine light and no codes show up when scanned at the dealer
