I've finally found the source of the rattling in my 86 740 gle M46. Below the headers and past the bracket on the tranny, there is a cylindrical metal piece that covers the main piping. There is a little bolt that comes off the reveal a hole where exhaust can escape just below the cylindrical metal cover. So, this piece spins around freely and causes LOUD rattling. I'm trying to figure out how this is supposed to be fixed. I was thinking about disconnecting the part of the exhaust just below and pulling the rear muffle and piping off to see if I can get rid of the metal cover, but I think things are welded, and i might not be able to get it off anyway. I am wary of taping it with exhaust tape because that isn't _right_. What is missing that allows the metal cover to spin, and how do i fix it?
Thanks,
Nathan

Sounds like the preheater hose holder assy (I think). Whack a coupla large hoseclips rouind it and clamp it up nice n tight. Should stop your rattles without the grief of having to drop pipes off. unless your zorst is nearly new you're asking for grief by fiddling. Muck about with 1 joint and 6 weeks later the next joint along is gonna blow. Such is life with old pipes...

Regards,

Big Rich.

Take a couple of stainless steel radiator clamps and clamp each end. I did this years ago and it still works. Just open the clamp up so you can put it around and tighten it up.
