- Hemi 5.7
Some of you may recall I did a top-end job on my 5.7 a couple years ago. After buttoning everything up, about 8 months ago I started getting the notorious "HEMI Tick". My first concern was the exhaust bolts snapped on these fresh heads. Naturally I procrastinated on checking it out. So the last 2 weekends I decided to get it knocked out. When I had purchased all the parts to do the head swap on my truck, I had also bought a set of MAHLE exhaust gaskets, but did not install them because the (re)manufacturer recommended using their complete parts kit, including gaskets.
I get under the truck and take the first side off and the gasket literally had fallen apart. Both sides were like this. I'm pretty sure the material is chromed/aluminized steel with a phenolic material "sandwiched" in-between. Problem is, since they're normal steel they still rust out, which is what happened in my case. This was after following the torque procedure and all. Thankfully, no exhaust bolts were broken. Now everything is buttoned up and my truck no longer sounds like a freight train. Down-side, my daughter doesn't call my truck a "choo-choo" anymore
TLDR; Buy gaskets from a reputable brand: MAHLE, Victor Reinz, etc.
Obligatory pic of the failure:
