2020 ram exhaust manifold bolts preventative maintenance ?

[jeffro2011]

So my exhaust manifold on my 2020 Ram Laramie with 35k miles is fine, but I know in the near future the bolts will rust off and break. Wondering if it’s worth my time to replace the bolts now before I have to try to extract broken bolts in the future? Any input?

I am wondering the same thing with my 2020 Ram. Has anyone had any success swapping them out with a better bolt and maybe some anti-seize before there is a problem?

If the manifolds have been heat cycled and seasoned for a few years,take them off and either sand them flat or have them machined flat,use Remflex 6022 gaskets and new bolts,and odds are they'll never give you any issues.But you need to remove them,and get them as flat as possible,before installing new bolts and gaskets.
If you don't have any broken bolts,nows the time to do it,before you have to weld nuts to broke off bolts

Same advice for 2023 5.7?

How many miles on your 23? You usually want to do this after the manifolds have quite a few heat cycles on them,and have taken a set

About all you could do is pull the easy pass side one off and check it for warpage with a straight edge,and go from there

Okay, thanks for the tip.

So is the idea you pull them off after they’ve warped a little and they just stay in that shape the rest of the life of the truck?

Exhaust Manifolds | Warped

I'm well-aware that the 5.7L HEMI has a fairly common issue surrounding the exhaust manifold bolts, causing the "HEMI tick". About 10 days ago, I noticed my truck had a tapping noise when cold-started. I assumed that this was the infamous HEMI tick and honestly didn't give it much thought. It...
