Did I just join the misfire club? Yes I did!

I think my first question after the engine replacement is how does this problem occur and what can be done to avoid it.

I do not think there has ever been a proven preventable care action other than normal maintenance and it just comes down to chance if it is to happen again or not at all.

One thing I will look into is the break in period on the new engine. The recommendation is first oil change at 5k miles which had me a little concerned because in the past we would make the first change somewhere between 500 and 1000 miles. I chalked up the change to the newer engine technology but now I'm not so sure. This time I expect to start right off with my own oil change at 500 and go from there.

Cannot fault your logic and say do whatever you think is best.

What I can say after seeing many oil analysis on the Pentastar to include on my own 4 or so Pentastar engine own vehicles, there really is no incremental trending wear across most OCI periods until it just decides to let go at a given mileage and then trends up rapidly from there.

So how do you go about getting that oil analysis?

Thanks. I ordered a test kit.

I will say if you are new to doing oil analysis testing, is to keep in mind that new engines generally take about 10K-15K miles of break in before wear materials flush out and trends level out. First couple of oil changes if you decide to analyze will show elevated numbers just from the manufacturing process.

Below is a thread I started on my own Gladiator with currently about 7 oil analysis sampled.

Yup. New to the process. Your sample data will be very helpful in seeing how things work.
My “old” engine is just under 15k right now but has a lot of metal in the pan that are causing the actuators to malfunction. I don’t know if they’ll try to see what caused that but I would like to know for my own information.
Kinda bummed but I’m glad they caught it while under warranty so it’s all covered.

It would be interesting to map out a few variables on motors that have had this failure. Things like oil change interval, oil brand, do you use the ESS.....

I'm one of those "old school" guys that still believes that the majority of engine wear happens at start up. ESS just seems like a horrible idea for long term reliability.

I followed the recommended break in procedure and had the oil changed at 5k intervals. I’m not sure where this one went wrong and you wouldn’t think you’d have to be overly cautious with it but I will be keeping a closer eye on it with the break in and initial oil changes which I will be doing myself.
At 15k I was on my last Jeep Wave freebie and it just so happened that the CEL came on at the same time.

So today I got this from my service rep

“Alrighty - so not the greatest news. But we checked the oil and there was a lot of metal in the pan, which means that it has contaminated the system. This is causing the actuators to not properly function, and trigger the check engine light. At this time, tech would like to replace the engine. We can get that done by the end of the week next week, Friday 7/26 at the latest. Luckily, we have access to an engine quickly. Of course, all of this is covered under warranty too. “

Holy crappola. Looks like I’m getting a new engine.

Damn. WTH? Yours is a 2023. I thought the issues were on earlier ones.

I just picked it up on Thursday.
As it turns out when they took the pan off and looked at the oil pickup tube there was RTV clogging the screen that reduced the oil flow enough to scrape the camshaft. I call that a random factory defect.
Here’s a pic of the tech’s notes on the work order.

I'm now in the breakin period and will go overboard with the breakin, I.e., for the 60 mile initial light driving I’m going 100 and for the 300 mile breakin I’m going 500 and will change the oil somewhere between 500 and 1000 miles.

Thank you. That's refreshing to read. It truly was just one of those freak things, and nothing to do with the engine design.

You’re welcome.
I said the same thing.
It was good to see the analysis on the work order and that it was a fluke.
I’m glad they found it.
