what have you tried so far to get them to seal. I always use high temp pipe thread sealant on the threads

there is only one gasket sealer i like thats permatex #2 it also makes a good thread sealer. i dont like rtvs cause the silicone acts like a lubracant and lets the gasket move. #2 doesnt do that, and it will hold up to all the fuilds under the hood.
