Side Sill metal insulation has a burnt hole... how to patch it?

[viper04blk]

I have removed the side sills, and both sides have a similar burnt hole in the insulation in the same spot. Perhaps the cat was touching them? None the less, what do I do about this hole? Do I patch it? Do I replace the entire metal insulation? There is a white powder inside the insulation, that I assume is asbestos... so I would like to seal it somehow.

Well I hope that is not asbestos!!!!! It's now one of the most dangerous materials out there!

I really doubt it is asbestos. I would pick up some aluminum tape at the auto parts store and patch the hole.

anyone think I could use exhuast wrap? would it stick to it?

[viper04blk]

Aluminum tape.... would that be in the exhaust section? or doe sit have another purpose? would the sticky portion of the tape be able to handle the heat?

[Bluecoupe]

Yes, it is in the exhaust section, and yes it should take the heat. It is sold as muffler tape

Yep, I use an aluminum tape on mine, works just fine.

How much heat reduction have you guys seen from insulating the side sills? And no concern about superheating the cats?

I Had the same thing and I used Metal Tape that they use in heating duct work, add several layers to that area.

I cant find exhaust tape anywhere that isnt epoxy fibreglass. I would prefer a metal tape. I can get some hvac type tape possibly... Its good to 600f. Is that hot enough?

But yeah HVAC should be fine too.

I wrapped fibreglass matting round the exhaust, excellent heat shield

Well, i figured out why I have these two burn marks in the same spot. The joint between the cat and muffler drips water for the first 15 seconds of operation. (my clamps were re-torqued before I started up)

I guess the 2 clamps are a sufficient seal for gas flow but can allow some water to leak thru. Then once its hot it vaporizes the moisture and has the moisture flowing out as a gas via the muffler. This is one giant assumption

Although, this was my first start up after 6 months, not sure if that would effect this hypothesis
