I purchased the “red” silicone gasket maker from AutoZone a couple days ago for my transmission oil bolt… just a question, will this stuff work with an exhaust manifold as a gasket? It’s rated at 600F I think or was it Celsius. Not sure but can I use this instead of a gasket? this is an oem header/manifold by the way.

 

to be honest with you it wont last that long

 

very well said it will last but i would only give it a month or two

 

can i reuse my old manifold gaskets?

 

Assuming they're in good shape, you can reuse the one at the head and the one between the upper and lower half of the manifold, but I wouldn't recommend reusing the donut gasket at the collector.

 

Better off just using the right exhaust gasket. It will save you trouble in the long run.

If they are in good shape sure. I have done it before without problems and mine were in pretty good shape.

I have since then replaced it when I rebuilt the motor but the gaskets came with some stuff that I ordered. If you have to reuse as long as it is in good shape I would not worry about it.
