    I've been out of the loop on things since I retired however, FCA knew the 4's needed improvement and it was being addressed. That's not to say they aren't reliable performers though. I agree on getting a carfax before buying. BTW, the 15 & up 200's are very nice cars if you can find one in your price range. One with the 3.6 would be a great performer.

    It is, the 14 Journey I finished today got 24 rockers, 24 lifters and the RT side intake cam. The cam was grooved from one bad rocker arm. If one went bad it was getting them all while it was open, they are all the same age.
    I will get some pic's of the parts tomorrow

    I've got a 3.6 in my '13 300, almost ready to hit 260,000 miles. Uses a little bit of oil, but otherwise it's been great! Spark plugs at 100K, did coil packs at 200K.

    I just turned 50,000miles on our 2017 Grand caravan with the 3.6 Pentastar and it’s a good engine so far providing good power, excelleration and fuel economy on the highway

    I like the drivability of the 3.6 in my 2018 Durango but I'm not overly impressed with the MPG's. It's AWD and is advertised to get 19-25. In reality I'm getting 16-23. Not a huge difference but not what I hoped for.

    I've heard that from other people too Peter. I bought it for trips so that's why I went for the 3.6. The only advantage to it is the $5000 dollar difference on the sticker price. That's a good hunk of change for 70 more HP. The worst part is it sits in the garage because we can't go anywhere. :BangHead:

    There are some vehicles that think are just too heavy for a V6. My Durango has the 5.7 Hemi, and I average 25 on the highways, and saw 26.3 on one trip. It does live up to the 12 rating for City driving.

    My '03 Dakota with the 3.9 V6 got 20 at its best. I was very disappointed! Then again, the EPA rated it at 19 Highway. Sheesh! The 4.7 V8 was rated at 19 too!

    I had a '93 B250 Van, 318 Magnum motor. I averaged 18 on the highway, and saw 20 on three occasions. Some friends bought a new '97 B1500 with the V6. Best they ever saw was 17.

    As i said, there are some vehicles that should just go with the V8.

    Here is a pic of the RT bank intake cam on a 15 Journey with a 3.6, 150,000+ miles, it had a tick and misfire on #5

    This is the RT intake cam from a 14 Journey 3.6 with 140,000+ miles

    The bad rocker arm compared to a good one. The needles wear, this one was froze to the cross pin.

    The one on the right is the good one

    In reply as I stated in my original post #15 the 3.6 gives you a better torque & HP ratio for the given the gross weight vs the 4 cyl. The greater horse power pays off in the real world city and highway driving. AWD will greatly effect fuel economy. The V6 torque & HP will get you up to speed more efficiently and maintain that fuel economy. As far as durability, the best engine oils of choice will reward you w/ fewer break downs do to oil coking, stiction and accelerated internal wear. Of course it all means nothing w/ a heavy right foot.

    I believe the durability all has to do with the customers oil choice and change intervals, I have yet to see a problem with a 3.6 in a minivan, it's been a 200 and Journey's and it's the same engine. Older vs Younger owners? Maybe the heavy right foot also:rolleyes:

    We drive the absolute balls off the 3.6 charger, it’s given us no trouble and I’m looking forward to seeing how it holds up.

    The only time my two pentastars went back to the dealer was for regular oil changes.
    Same price as the fast service joints and car was usually done before I finished my coffee.

    What are you using for oil and what are your oil change intervals?

    Well up until recently we have just brought it into the dealer at the recommended intervals, 6000 miles I think. Now I’ll be taking over the oil changes as it’s out of the warranty or whatever. I have to do a change in ~1000 miles, have to consider what oil I want to go with.

    My folks run a minivan with the 3.6 and trade out vehicle's with around 120 to 130k. They drive cross country in their 80s as they won't fly.. I am concerned about them doing this, but not the reliability of the van. My .02
