[T3] I've got another question , same one I asked a while back.

[Dave Hall]

 I had to do the MIG trick maybe 10 years ago - it's still holding up, but
it is the stock exhaust.

You have to be careful to seal off the rear of the large heater boxes to
prevent any leaking exhaust getting in around there  Originally there's a
large clamp and packing around the pipe to stop exhaust leaks getting into
the heating system, but mine had more-or-less rusted away (parts 14 and 15
on http://home.clara.net/hallvw/type3/T3pbo/T3pb2-12.htm .)

________________________________
I had a heater box where was pitted bad like that and would not seal.  I
cleaned the end up and tack weld all the big pitted spots with a MIG welder.
Then took a grinder and smoothed it out. I still had to use a little muffler
cement because I couldn't get it back perfectly round agin but not near as
much as I would of if I had not used the welder first. If you could get it
on a lathe of some sort after welding it then that would get it close to
where it should be as far as the roundness.  Fortunately I found a better
heater box in all my mess of VW parts collection so I will be swapping it
out soon.
