    Header rattle

    Does anyone know of anything you can wedge into 1/16" gap that can withstand high temps? I've been chasing a couple rattles down in my spare time since I did my headers last year. I finally found the last two, both of which are off the small pipes from the block, to the collector. Ones just behind my passenger side wheel well, where one of the small pipes rubs, and the other at the firewall on the drivers side. My lift has been out of commission for awhile, and it looks like it won't be accessible anytime soon. I really miss it right now. I was thinking of maybe gobbing a bit of high temp gasket stuff at the contact points, but don't know how wise that would be.

    Any advice from the pro's would be awesome, or any others who've had these issues!

    Exhaust wrap from DEI might do the trick -- comes in rolls. If you have stock motor mounts they may have sagged a bit. A set of poly replacements will lift the engine back up where it needs to be a give you a bit more clearance.

    I thought about replacing the motor mounts while I had it all open, guess I should have. lol I'll give the wrap a try, if I can find it local. Got burned internet shopping a couple months ago, so taking a break from it.
