I know that the 2014-2020 3.6 Pentastar engines have lifter tick problems due to bad rocker arms. I have a 2016. Do the 2021-2022 Pentastar engines suffer from lifter tick or is it too early to tell?
No, the Dodge Grand Caravans have this problem as well. There is a class action lawsuit regarding this issue. Chrysler does not have any upgraded parts. If you repair it, you just put in the same faulty parts. Just had an estimate on my GC. $3500 if they have to replace the cams (along with lifters and rocker arms).Our Pacifica hasn't experienced this yet at 92k miles w/Pennzoil Platinum 0w20 following the OLM since 40k. Probably on bulk oil following the OLM prior.
I thought the main issue with this and the pentastars were on the Wranglers.
2017What year model is your Pacifica?
Did you have to replace the cam shafts or just the rocker arms? I’m thinking that I may just have my shade tree mechanic replace the rocker arms and lifters.The problem is the main pin in the rocker arm that the roller rides on wears down. This is one out of my wife's old vehicle. I replaced two of them between about 115 and 123k miles. I couldn't replace them all because they were on a huge backorder at the time, which is not surprising.

Here is the condition of the engine/underneath the rocker cover at the time. It was spotless.

What oil weight are you using? Can you slightly increase viscosity to reduce lifter tick?I know that the 2014-2020 3.6 Pentastar engines have lifter tick problems due to bad rocker arms. I have a 2016. Do the 2021-2022 Pentastar engines suffer from lifter tick or is it too early to tell?

Why is this issue so much more rare on the Ram 1500 trucks?
It is my understanding that it was poor metallurgy. But I could be wrong.I’m following this thread because a camper van with this engine maybe in our future.
Is the issue due to poor metallurgy, incorrect oil specification or both?
Thanks.
Why would anybody think that after umpteen years of the same stuff that FCA would suddenly care enough to change now.I know that the 2014-2020 3.6 Pentastar engines have lifter tick problems due to bad rocker arms.

It is my understanding that there is a Pentastarvand a PUG, Pentastar Upgrade, that is used in other vehicles besides the minivan. I haven’t researched this thoroughly as I have switched brands for my transportation needs.Why would anybody think that after umpteen years of the same stuff that FCA would suddenly care enough to change now.
I think it's that and the area where the rocker rides is just too small . But I'm no engineer.It is my understanding that it was poor metallurgy. But I could be wrong.
