Interesting observation. Like I said I've heard quite a few newer vehicles that make that same noise. I'll hear it not quite as pronounced in my 3.6L Pentastar, but it would have to be sitting a few weeks w/o being driven in order to make that noise. Then the noise will last 1-2 seconds at most.
The lifters do leak down, which they claim causes the noise and it is supposed to be "normal." I guess "normal" can mean a lot of things.
Yup, parked at the streetside of my work, which is at an incline. 13 hours parked, cold start, about 6-8 seconds of rattle then back to normal.
This was while running Conventional Formula Shell 5w20 and a CQ Red. I havent had that issue since, but I no longer park there anymore, maybe I will and see if it's still an issue with the current fill, or whatnot.
I've mentioned this a few times here. I have a friend who is an A-tech at a Jeep dealership. He is an excellent tech. He has handled the cam lifter failures and has worked with Sr. techs Chrysler sends out to the dealerships to troubleshoot issues. Long story short these cam lifter problems are not unique to Chrysler products, and contrary to what many on Bitog believe they feel higher ZDDP oils or tweaking the oil with ZDDP can help, yes even in engines like yours and the 3.6. They also feel moving up a grade to a 5W30 is a good idea too. The problem is they can't openly suggest using a ZDDP additive, or going against the owner's manual. I have discussed this on numerous occasions with a few highly respected members here, they agree. Having said that if a person has defective parts, nothing is going to help. Good luck!!
