RE: 325i (E30) Ticking When cold

[Thi VanAusdal <tvanausdal@xxxxxxxxxxxxx>]

Hey,

 I too have a cold startup exhaust leak - from
the exhaust manifold/flange joint.  It is
probably a crack in the pipe where the flange
is welded to the downpipe going to the catalytic
converter.

 This failure, I believe, is a byproduct of the
exhaust bracket being missing near the cat which
connects to the transmission.  The extra movement
stresses the flange weld, and it cracks.  I had
a '80 528i drop its entire exhaust front end b/c
of this failure.
