Wife's brand new North edition suddenly has a nasty rattle coming from the passenger end of her 2.4. Being a Jeep Wrangler man, this new motor is totally foreign to me (no pun intended). At first I thought it was just a loose guard because the motor fires and runs perfectly with no engine service light and the oil is still on the top of the dipstick and clear. It was picked up off the dealer lot with 35kms on it and now only has 3600kms. It's now at it's 2nd dealership, the first had it for three days and never touched it. The 2nd dealership has it booked for Monday morning. Can anyone give me the low down on what's at that end of the motor.
I'm guess the time chain is located here but can't really get a clear look at the block. Just would like to know a little so if the dealership tries to "bull" me, I can call them on it.
thanks for anything you can pass on to me

topbanana,

I'm sorry to hear about the noise you're experiencing.

Is the rattling heard constantly? Does it change at all, depending on the speed?

Your Jeep dealer is factory trained to address such concerns and will be able to pinpoint the root cause. Their focus is to address any concern you have and resolve it. Be sure to speak with the Service Manager if you have any questions regarding the diagnosis.

Just a quick update - the dealership brought it into the service bay for a listen and now have decided the problem is in the top end. Put the wife in a rental and will begin teardown tomorrow.

Now going into week 4 without the vehicle. First diagnosis was a couple of bad rocks. Waited a week for parts to come in only to have mechanic find the cam was scored when he started repair. Now awaiting a cam.

topbanana,

have they given you an ETA of when they will have the repairs completed and will get the Jeep back to you?

I'm not sure what the lemon laws are in Canada, but I had a car bought back in WA state after being in the shop for over 30 days with the same issue unresolved within the first year of ownership. I would look into that if it's a possibility where you live, good luck.

And it just keeps getting better, cam came in but now they've found damage
in the lower end. Once again awaiting parts. Dealership's mechanic is making a career outta this one. Should have pulled the motor and installed a crate one, not going to be anything not pulled and repaired/rebuilt left!

Well it's finally together and back on the road - so far so good.
A quick parts cost lookup comes in at over $3000, one actuator part racking up $900 alone! Mechanics notes indicate the root cause of all the damage is the key used to hold the crank's timing gear sheared/came out. Noticing the exhaust tone appears to be louder but it;s been gone so long, maybe I'm imagining it.

The 2.4L Tigershark is a widely used engine across several models and nameplates, and for the most part they tend to be reliable with no chronic issues. Sounds like you just got unlucky.
