hey everyone im re installing my stock intake manifold and im running into a lot of issues. number one, what seal or seal's should I use. Number two what is the full prsedure on doing this, ive heard many ways and I tried doing it today and I basically had an epic fail. I couldnet keep the gaskets in place and the seal some guy at the store told me to use was orange and made a huge mess, plus it was silicone and i thought that you werent suppose to use that. I need help!

I use Permatex aviation sealant on the manifold to head gaskets, and on the front and rear galley seals, and especially the corners when they meet.

Some people have so much trouble with the end seals they don't use them, they just use a thick ribbon of silicone sealant. This is not just a Ford thing, if you look closely at the stuff you have you'll see it's Chevy orange. The sealing surfaces have to be absolutely clear of oil, grease, or dirt.

so do I need Hi temp or will any silicone sealant work? also how long do you let the sealent dry before atatching the gasket?

let your sealant set up at least 15 min. go to homedepot or lowes and get four long bolts (4-5"), i believe the manifold bolts are 3/8", but I might be wrong. cut the head of the bolt off. now install them at each of the four corners where the manifold bolts would normally bolt, hand tight. install your manifold using those bolt shafts as guides. this will let you drop your manifold straight down without moving all over the place and making a mess. once in place, simply remove the bolt shafts.

- Any parts store has an intake manifold gasket set.
- put a thin coat of sealant around the water jackets located at each end of the gasket, both sides
- the small metal looking gaskets are for the cross-over at the center of the manifold gaskets.
- the galley gaskets usually require a gasket adhesive (rubber cement) to hold them in place. Most people bypass these gaskets and just use silicone. if you use the cork galley gasket, be sure to put sealant at the ends where it meets the head gasket. if you use just silicone, make sure the bead is at least 3/8" tall.
