Intake gaskets - Sealant / Loctite
A friend who's a mechanic said I should use some kind of sealant on the gaskets when reinstalling the intake. So I drop by the store and they send me home with a bottle of Loctite 5923. The bottle says it's flammable and all kinds of scary stuff so I wondering if it's a good idea to use it for this application.
What do you think?

Eivind: Tha manual never specified weither of not to use a gasket sealer/loctite, but what i can say that you are better off installing them dry.
The only "problem" is to keep those gaskets from moving when re-installing the intake, i used both a red high temp loctite and grease when i removed the intake twice last few months (and recently).
I would stick to giving a very light coat of grease on the intake, and install the gaskets on the intake rather than on the cylinder head.
That loctite stuff was a bit of a pain when removing IIRC, i would keep it simple

Be it right or wrong, I sprayed mine with a light coat of the permatex coppercoat gasket sealer.
I uses it on every gasket with the exception of the head gasket, Install the H/G dry.

I wouldn't do it - but I am always playing with the thing, and I wouldn't want to have to jackhammer the gaskets off. You can center the gaskets with a punch while you install if they move around.
I have pressure tested to 40 psi with no glue - holds it fine.

I normally use Loctite 518 if I need to. Flexible. Temps are good to over 300F. If I need to reuse old gaskets I use some. A small amount used as a ring around the sealing area works well.
But if they are new. DRY.

Yes, dry is best. I use a little blue Loctite on the intake manifld bolts, just for insurance.
If you are going to use anything on the gaskets, Permatex Hylomar is a good choice. This stuff never drys, so the gaskets come off beautifully next time you pull the manifold. A little brake cleaner and the surfaces are perfect [well, as perfect as they were the day you smeared 'em with the Hylomar].
