Chrysler 3.6L Pentastar Ticking Noise & Repair Options

Chrysler 3.6L Pentastar Ticking Noise & Repair Options

In this video I feature a Chrysler 3.6L Pentastar engine that has failed rocker arms. This failure is somewhat common for this engine. In the video I discuss how the rocker arms fail and other issues that may be caused by this failure while showing the parts that are affected like the camshafts, cam bearings, and lifters. I then talk about possible repair options depending upon the severity of damaged caused.

Note: While this video is somewhat detailed it is superficial in several ways. This is not a detailed step by step how to guide for properly diagnosing and repairing your vehicle. The video is meant to be a very high level overview of the issue discussed and to present possible repair options only. This video also does not cover all possible scenarios that may occur. Other repair routes may be needed depending upon the condition of the engine and the results of diagnosis. Also, the damage shown in the video may vary greatly compared to your own vehicle. If you are not confident in your own abilities to diagnose and repair your vehicle it may be best to have a professional tech diagnose and repair your vehicle for you.

Also, I believe that there is a TSB for this issue on the earlier 3.6Ls. It never hurts to contact your dealership to see if there is some kind of extended coverage or assistance for this issue. (judging by the chatter online.) You may be pleasantly surprised. Who knows?

By the way, the engine in the video is going to the scrap yard. I normally would not set a cam on top of the engine as your saw at about the 5:00 mark. This could damage the cam and the mating surface that the cam is sitting on on the head. (It’s at the top of the screen.) Be kind and gentle with cams. Set them on a pillow or some sort of pad if you can. You don’t want to damage the lobes or the cam journals.

I’ll post a link to the tear down video of this engine when it becomes available. At this time, It’s still cooking.

They corrected the problem sometime in 2014. After that they were solid engines. The transmissions in that era got much better after 2014 as well.

@stevesapir says:

Outstanding video man. Thank you!

@Rincon009 says:

This is great!! Thank you!

@thomaslanik7215 says:

Wow! Thank you

@vulgarhyena9616 says:

These followers fail due to poor quality roller bearings, HOWEVER I see them fail mostly on fleet (high idle hours) and poor oil change intervals. Customers who do oil changes at 5,000 or less miles rarely see this issue. Don’t listen to 10,000 miles oil change interval lies. Learn to change your oil yourself, save money and your engine.

Thank you, this was really great information..

My 2017 is making this noise after hitting 100k

@valerioporcelli says:

Very good video. Now I know why my 2012 TnC makes that noise

@isaacnichols12 says:

Great information!

@kristopherhasenbuhler5393 says:

Im caught up between rebuilding the engine i have and rebuilding a low mileage Junk Yard engine,

Either way I ONLY WANT TO DO THIS ONCE!!!

@jehadabunaaj1564 says:

This should be recalled

@richardcotreau1653 says:

Yup 2017 failed 72000 miles

@papabits5721 says:

It looks like the engine was looked after

@7628739 says:

Buy the new rebuilt motor

@PodDeep says:

Great video.

Chrysler new updated rockers are now made in Taiwan vs China

@markrombouts4142 says:

Hi,

I have a 2016 ram 1500 3.6 with an engine tick for the 4th or 5th time.
The first time the dealer replaced the passenger side cams, rockers and lifters under warranty.
I changed 5 rockers over a period of 100k miles and was always able to hear with a car stethoscope what side was ticking.
Now I have a tick again but the valve covers are quiet but the tick is coming from the exhaust close to the manifold?
Anyone have an answer for this.
170k miles, every 6k miles oil change with Pennzoil.

@EthanB-i6o says:

FANTASTIC TUTORIAL. VERY COMPREHENSIVE AND ARTICULATED.

@NPartipilo says:

Excellent video..

@uccoskun says:

I believe lifters have a small spring in it and mostly pushed out by oil pressure. I would press on the lifters with my finger and watch them collapse under pressure. If it is not collapsing, it is frozen, and not good. If it is collapsing, I would keep using it. Am I right in my statement?

You know somewhere, somebody knows exactly why all these roller followers are failing prematurely. It reminds me of the same issue present in the 5.4L 3 Valve ford engines (which are notorious for Cam Phaser and timing chain guide/tensioner failure). Ford Tech Makuloko did a great set of videos addressing the followers failing on those engines as well, and this feels right similar. I would say poor material quality in the follower bearings (and likely the cams as well) is probably to blame. It is no secret manufacturers choose quantity over quality for mass production. AKA these followers using cheap questionable materials, along with the recommended oil being basically water these days (5w20 or 0w20) and i would say you have the perfect recipe for failure.. now i know somebody is gonna chip about my comment so go ahead, chirp all you want. But with what i have observed over the last 13 years there are so very few engines being made these days that can even come close to what was produced prior to 2010~ the actual metals being used in modern engines have been reduced to 'bare minumum standard' just to get you through the warrenty period.. Do you actually think manufacturers care about how long your engine lasts?? LOL dont kid yourself, they only care about $$$

@tommyclarence6809 says:

Good job❤

@jjgg7264 says:

I just had the rocker and lifter issue fixed on my 2015 grand Cherokee with 128k miles. Cost me $2600

@ut_punkn1859 says:

My 2020 still has a ticking sound when you get up to 2600 rpm
