Re-Using Downpipe Gasket
Pretty simple question, I just recently re-isntalled my turbos with all new gaskets from mazda except for the downpipe gasket. I thought it looked alright and I didnt really have the money to spend on a new one.
So last night I started up my FD and there seemed to be no exhaust leaks, but after 30 seconds lots of smoke started pouring out of the engine bay, from what looks like around the downpipe.
So basically my question is, can I re-use the downpipe gasket?, should I add some sort of a high temp sealent on both sides? Im assuming its not working because of all the heat cycling it went through before, but I dont have quite enough for a new one.

Yep, one of those layered metal gaskets. Seemed to be pretty straight and not coming apart.
This copper spray, can I just go to my local auto parts store and ask for a high temp copper gasket spray? Or is there a specific brand?

When I reused mine I cleaned it off really good making sure there was no carbon build up on it with a wire brush. Then I used alcohol pads to clean it off before reapplying. To get that much smoke you would have to have a pretty big break in the seal tho.

You can basically get the copper spray from any auto parts store, it's made by Permatex.

There are many things I make sure is "authentic" or "Mazda OEM", but Exhaust bolts is Def. not not of them.
EDIT: Oh ok, I thought he was talking about the rest of the exhaust, not the actual downpipe to engine. Yeah I would do some sort of OEM or harder core order online bolt for that.
