Default Silicone Caulking

Any recommendation for type of silicone caulking to seal up for air leaks that will hold up to heat also?

Thanks

Use permatex blue silicone gasket maker that is sold at most auto part stores. I use it to seal up my nitro engines, and it works good.

You should be using the stuff in the gold tube not the blue... It says O2 sensor safe on it... It stands up to the heat and fuel...

THIS is the correct reply.

The Blue gasket RTV silicone will not be able to keep oil and fuel from wicking through it or gumming it up as it is usualy used on air intake manifolds or in places that are not normaly in contact with gasoline or oil. I only know this because I worked at GM BUICK dealership and the mechanics swore by it and we were always out of stock at somepoint on it... so I guess I was actualy Sworn AT... LOL....

The guy that does the motors for VSmodlesports told me to use a GM silicone product. Not sure on the name, but this is what he uses on all his motors he builds. This is what he used on the motor that won the sedan race at the US nationals, so it has to be good!

The best silicone I have ever come across is the one that VW uses on their oil pans from factory, you can go to any VW audi seat or skoda dealer and ask for the oil pan gasket maker, Its a little bit expensive but its the best by far.
