2025 Ram 1500 SST Engine Tear Down

Cooled EGR on a gas engine. Awesome. The diesel guys will tell you that there's totally nothing that can go wrong with this.
That may be possible in Texas, but here in the Midwest where they salt roads like margarita rims, you’d have had a pile of iron oxide and then the engine block and trans in your driveway. Like every other Ram of that era. The Cummins trucks were a 500k engine in a body that may last 90k

I was wondering similarly…. They removed how much of the truck to get to the engine?!?

So??
Dual row chains on I6 engines can last more hundreds of thousands of miles than anyone will ever care…
Yeah your right, I missed that.
Right? My Ranger has one too and that's about the only thing that worries me about the 2.3
Is raising the cab actually necessary or is it what the book says? From what I have read you don't need to pull the cab to remove the 6.7 head.
Unless that EGR cooler is strapped to a 6.0 or 6.4 Ford diesel, I would not be worried just yet.
I have no issue with a DOHC cam engine. I was just noting that the timing chain was not that short thing in the OP’s pictures.
So? Does the Hurricane DOHC I6 have dual row timing chains?
Edit: it does not
Some engineer got a big bonus for designing it with those bolts preventing removal.

Well that’s annoying. Thought we learned against single row chains in the early 80s…
Thinking it may be a production line require related to engine / transmission assemblies mating process.
Agree. Time will tell if it's a stout running engine. Blown turbos at 3K, valvespring failure, etc.
That's what I thought too, but I'm not buying it. You've got all the room and all the fixturing in the world to line up the engine and trans in the factory, there's still no way you need those studs to be that long.
Right and if they can save 10 cents a stud, they would. They didn't spec that length unless it is for a purpose.
Stellantis ¯\_(ツ)_/¯
It is easier to work on with out the can in the way and saves your back. You can get a cab off the frame in under an hour.
The truck is getting a factory long block. Here are some head pictures.
