I sent an oil sample to Blackstone and it came back with really high iron and copper numbers. Including the factory fill the last oil change was the 4th oil fill in the engine. My truck has the infamous lifter rattle on startup.
Did yours do it every time or just once in awhile?Copper is a little high but I wouldn't be worried yet. I attached the last sample on my 2016. Also my truck sounded just like that, same short duration as well and it was broken exhaust manifold bolts. Would have never believed it since it only lasted a few seconds at most, but no noise since I had them replaced under warranty. Mine were broken at 35k miles.
I have multiple times. They won't fix it.That is really, really bad start up noise. I’d take it back to Chrysler. I’ve heard it a couple of times on trucks that had sat for a long time between starts, but if this is driven regularly it should not sound like that IMO.
Initially it was just every once in a while, it gradually got more frequent then once it finally did it for a solid 10 seconds which got me to investigate. Its normally the bolt closest to the firewall on either side that breaks. Dealer told me my back bolt was broken on both sides. On the passenger side I could reach in there and feel that the heat shield was loose on the back bolt since it was broken.Did yours do it every time or just once in awhile?
I was thinking that too, I slightly thicker oil (a W-30). Maybe Magnatec?Try a 5W30 like Mobil 1 or Castrol and a NAPA Gold oil filter. If that doesn’t cure it, find another dealership.
Yep, many people on the various RAM forums have tried the Red Line 5W30. It’s helped with some owners. That’s the reason I said to go with a 5W30 oil and a WIX/NAPA Gold oil filter.I don't know if any oil viscosity will resolve that. Not even Burla's (bitog member) Red Line or high Moly recommendations.I'd find a new dealership or RAM independent specialist.
OP, if you're set on trying an oil "remedy", look up Burla's posts using the search feature or try the new Valvoline Extended Protection. It's a very high Moly oil. I have my serious doubts though. Best of luck.
I got a phone call and didn't realize I hadn't finished my post before I hit "post reply".That's definitely internal. Something is either loose inside the engine or somethings

Did Burla post an analysis of that oil? I'd be very interested to see the moly levels. I tried searching and couldn't find anything. Is the search feature here still goofy?look up Burla's posts using the search feature or try the new Valvoline Extended Protection. It's a very high Moly oil. I have my serious doubts though.

This is it after it's warmed up.
