E36 insulation between exhaust & firewall

Greetings everyone,

I have a 1994 325i E36, and noticed a burning smell. Looking under the
hood, I can see that there is some kind of heat or sound insulation
that has come loose from the firewall and is resting against the
exhaust. I has a kind of foil layer on the outside that has turned
brownish in color where it contacts the exhaust. I can't see how it is
supposed to be attached to the firewall. There is a second piece of the
same material adjacent to it and is still in place, but I can't see
where it attaches either. Does anyone know how these attach to the
firewall? Were they perhaps put on with some kind of an adhesive? If
so, what would be an appropriate adhesive to use to re-attach the
piece. I'm assuming that it would not be wise to just remove it, but
correct me if this is not the case.

Thanks for any suggestions.

David

Usually they're help on with screws and very often the foil cracks and
they come loose. Check with www.realoem.com for pictures.

Try looking at the parts breakdown for your car in the official BMW ETK
parts list. There is one online he

Thanks for the info. That site is an excellent resource that I can use
for other things, as well. It looks liike I will have to get to these
from underneath, but the ramps I have are too steep, so the nose of the
car hits the ramps before the tires. As soon as I can get the car in
the air safely, I'll try to use a screw and fender washer to get them
back in place.

Thanks again.
