I use Permatex liquid the Red in the small brush on can,he one thats reall sticky and you get it all over your fingers,and it cured my leak,also had good luck with black permatex silicone type in tube Hi Temp,pu t a good coat all the way down one side of bolt then a dab under bolt head should seal it up.suppose you could make little intake bolt gaskets-LOL.make sure the bolts and thread are good and clean befor applying anything maybe spray with carb cleaner or brake clean just dont get in eye it burns!
