You have to remove the intake and toss the friggin' cork gaskets. Just use a nice bead of silicone on the ends instead. It's a very common issue with cork gaskets. I like the Mr Gasket intake gaskets better than the Felpro ones IMO....but whatever they carry at you parts store will suffice.

100% pure, NOT fortified with silicone. I have always used just the 100% ORIGINAL clear silicone.

Don't get carried away with to much, don't want excess dripping into intake valley.

I throw away the cord end gaskets and use Permatex UltraBlue or UltraBlack. Never had a leak since. Other silicone sealers do NOT adhere well, especially if they are exposed to gas/oil.
