Not classic Mopar, but for those that run the venerable 3.5L or 4.0L V6, sooner or later the "Death Rattle" will come your way. It's a ticking sound coming out of your engine. The cause is the rocker arms and it's a well documented problem that the dealer SHOULD have fixed. In my case, the dealer did not fix it and in my 2010 Challenger, the 3.5l Death Rattle started at 100,000 miles (out of warranty) and I let it go. Now at 215,000 miles I got the upgraded rocker arms and dug into the problem. Simple fix it should have been. It now is not. See pic for what happens when the Death Rattle is allowed to go on. Need a new passengers side cam now.
