2017 ram 2500 broken manifold bolts
Manifold bolts are easy to get to. Even when needing to weld a nut to the broken piece to get it out, there's plenty of room. The driver side is a little tougher because of the steering column and dipstick tube, but really not bad.
Check the joint in front of your muffler, every person I know with the newer style Ram has had a bolt break at the joint causing a leak. It's pretty loud at startup but eventually seals itself up. The ones I have heard are louder than the manifold leak, which usually just tick when cold.
