I'm 2 months out of warranty and at 100,839 km and the dreaded exhaust tick just started on the passenger side. Going to call the dealer but I'm pretty sure I'm screwed.

Called the dealership and the service tech told me to try some octane boost or 89 fuel to see if the tick goes away. What a joke!

If you try the octane boost, make sure you buy boost rated for the right side of the engine, if you buy Left Side Octane Boost it might not work...Called the dealership and the service tech told me to try some octane boost or 89 fuel to see if the tick goes away. What a joke!
Yes. I watched the tech do this at my dealer. Take a socket and ratchet. He used 1/4" drive with a short ratchet. Start on passenger side. If you can turn the manifold bolts "easily" they are broke and being held in place by the manifold. On the passenger side they are tougher to get to. Same check. To confirm exhaust leak versus lifter noise. If your first cold start in the morning is the only time you hear it and it goes away after the engine warms up. Pretty good chance it is exhaust. In the 5.7 the common bolt to snap is the passenger rear. They tend to fall out from vibration.Aside from the tick, is there any way to tell if the bolts are broken?

One way you can tell besides tick, is when you first start it up after sitting(engine cold) and you start to drive idle will come up high and seem odd, then within 30 seconds go back to normal. This has been a ongoing issue with hemis since they came out, my 05 Durango hemi, broken bolts too. Cast iron and aluminum don't expand same so snaps bolts. Is why many just do shorty headers.
I think the main reason it helps is when the headers warp they don’t have the strength to pop the bolts like cast iron does. It might be that the aluminum heads and the cast iron are not meant to be. I am not sure entirely but it is a big problem and should be reengineered if you ask me.
can't you replace them with better bolts?
This subject gets me going. I installed a remote start a few weeks back. Never had this issue till now. I got 71k n no warranty. WTH. 2016 they screwed up on the warranty @RamCares. If you could help me get these replaced under warranty that would be great. This has been a know issue and continues to be a problem even on the 2018 models!!
