I use permatex aviation form a gasket $5, never had a problem with that, someone else might of but if its ok on planes i think its probably pretty reliable

You could look up its specifications, all permatex products have their details on line. See if it is oil/petrol resistance and if it has some form of heat resistance. If it meets those criteria then its very likely good for that application you need it for

I vote for Permatex No. 3 Aviation-Type gasket dressing as well. Been using it for years, works great!
