Subject:      Diaphragm Springs - Exhaust - 2.1L WBX
Content-Type: text/plain; charset=UTF-8

I have run into a problem. The J-pipe has broken right at the 2 into 1 cast
iron collector. I have a replacement.

Upon close examination, it is clear that break is an expansion stress
break. Also, it's clear that connection is supposed to be an expansion
join. But like the 'lil boy  sez "It ain't happening!" Therefore I have a
broken J-pipe.

Bentley ( page 26.9) shows that joint assembled with 5 DIAPHRAGM SPRINGS on
each of 3 bolts. Mine has none. So far, list vendors I have contacted don't
use or sell these, so they say, and haven't seen them. I have a problem
with that, because I KNOW that is an expansion joint and has to have a way
to relieve the stress of expansion due to heating and cooling.

Can someone enlighten me about this? Tell me where to get Diaphragm Springs
- by that or another name?  I don't want to put this back together unless
it is right and can give under heat in that joint.

Thanks

John
