I've been having the same symptoms, what did you end up finding. I also used red silicone so I'm going to install the gasket first. Injector only has about 3k miles, so I don't think it's that. Code usually comes on after warm up when the truck sits for at couple weeks. Otherwise it doesn't come...
The only oil I would use is rotella t6, 5-40. When I bought my 2016 there was a service bulletin to remove the euro oil and replace it it with rotella. They thought that was the issue with crank bearings. So that's all I use

Did you have any change in the oil level? I'm hoping its EGR, much simpler repair. I'm still fixing the def system from the exhaust bolts breaking and melting the def line and injector. Bought a cheap injector on ebay but it was defective. So I bought a new injector from RAM , just have to...
I don't see any coolant leaking anywhere and I used an overflow tank full in about 2500 miles? thinking maybe the EGR cooler failed again. Anyone have that happen to them? thanks
