Has anyone heard about this warning for 2014 and UP 3.6 Pentastar oil cap valve malfunction?

Never mind it’s Amsoil rep talking, he’s explaining there’s cause for concern for our oil caps as there is a faulty valve issue in there.

I have been aware of what was mentioned in the video for some time now... actually for almost 3 yrs now.

It is not that the current oil fill housing cap has a "faulty valve" but rather IF, if you do not pull off the oil filter element properly, you can damage the actual valve in the oil filter housing cap.

There have been a couple of posts in the JL Wrangler forum over the last 3 years where guys have damaged the oil filter housing cap so bad the valve fell apart/fell out of the cap itself... one guy actually, foolishly tried to put the valve back together and continue to use the oil filter housing cap.

Anyway, the wise JL/JT owner with the 3.6 is prudent to always keep a back-up oil fill housing cap
on hand, just in case the inner valve gets damaged or the oil filter housing cap cracks when tightening. Mopar Genuine 68191350AA Engine Oil Filter Housing Cap

I was worried that might be the case. They will make one for ours if necessary. Maybe Mopar redesigned the cap. Will look next time I change oil.

Watched the video. Seems like a guy trying to sell amsoil filters. Doesn’t know the difference between psi and psid. His description of the other brand filters is not correct. But it is an interesting design for a bypass valve.

Guessing the new design was to prevent the failures of the first design. Don’t see much about failures with the new design on the net.

But thanks for the heads up and it is definitely something to keep an eye on.

At 10k now and after Pepe had posted the part# on the oil cap I ordered it to have a back up. Received it yesterday and did my oil change. My first oil change was at 1,000kms and replaced the Mopar filter for the Amsoil one. Took a sample of the first oil change and the lab found a “trace of glycol”. I anxiously waited for the 10k to come for the oil change and have the sample going in on Monday. If no glycol is found here, the factory used contaminated oil. We shall see.
Here’s a couple pics of the Mopar filter (top) vs Amsoil (bottom ).
Was more careful to pull the filter straight out and also put back in. (Never had to think about this part or I’d break something).

That is not at all evidence the factory used contaminated oil and people really need to stop freaking out about traces of things in their oil that aren't indicators of wear. There are maximum allowable values of everything including toxic elements and rat shit in your food. Glycol is a component of nearly every coolant on the market so its presence in a new engine isn't unexpected. If you start to see more than trace amounts then I'd worry but trace amounts aren't going to impact the efficacy of your engine oil in any significant way.

Maybe. The thing about oil manufactured and bottled or sealed is that it doesn’t contain glycol. Glycol in engine oil is not something you want to see even if it’s “trace amounts”. Kinda like blood in your urine. Glycol in the oil, even trace amounts is, (1) corrosive, and (2) it says something. Either the Pure manufactured oil is contaminated at the factory(because glycol isn’t added during manufacturing) OR there’s an internal leak in the engine. Both scenarios, to me, are important. Kinda like blood in your urine.

Nobody here is freaking out. I gravitate toward information and details that prepare.

Got the 10k engine oil sample test results back from the lab this morning. They found glycol in the sample again. Lab suggests there’s an internal coolant leak which requires immediate attention. Problem solved!
