Exhaust gasket
 

I been running thru exhaust gaskets here lately. Who makes a good exhaust gasket for .12 engines. I'm currently using Nova gaskets on all of my Novarossi based engines.


Pass you soon ...

how fast are we talking here??
I thought nova gaskets were really good quality? :D
Maybe there's too much vibration causing the header to move around too much on the gasket, eventually weakening it prematurely? O.o

The question is which part is failing? I was using a brand not to be named and the header was cutting through the flange portion of the gasket and I switched to rossi and they work well. The only thing I wish they would do better is have the diameter stay the same on the part which inserts into the header. But I have yet to find a brand that doesn't do that.

I would go thru one a club race. It always tore near the tip of the engine exhaust never at the flange. But since you mentioned it; my spring is somewhat loose I might have some vibrations there. I changed it today at my club race. It still looks good. I will see what happens next week. Thanks for the tip.
