intake manifold end gaskets
The aluminum intake manifold gaskets on a 327 keep sqeezing out and leaking after it is ran for a only a short period of time. Do any of you guys have any idea why this could be happening. I have even tried silicone on the gaskets. Any help would be appreciated. The engine year is 1966. ThanksLast edited by qhkajlog; 03-31-2004 at 12:51 PM.

I always put em' in dry with just a dab of silicone in the corners where they mate with the port gaskets. Make sure everything is very clean & dry. Never had trouble doing it that way."PLAN" your life like you will live to 120.

i throw mine away & use about a 1/4 inch of black silicone gasket sealer on it, instead of the gaskets. It must of been a big problem cause if you get a gasket kit from a Chevy Dealer & even some aftermaket kits, they give ya a small tube of sealer instead of those funky gaskets......joeDonate Blood,Plasma,Platelets & sign your DONORS CARD & SAVE a LIFE

I'm with cousin Joe on this one too. The sealant in a tube makes a "perfect" fit, and you can trim off any excess that bothers you with a razor after it cures. If your heads or the block decks have been milled (and the intake hasn't been shaved to compensate) it can sometimes make the fitment of those annoying seals real aggravating.Your Uncle Bob, Senior Geezer Curmudgeon
It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.
Luck occurs when preparation and opportunity converge.

What Uncle Bob says is true. I had my heads milled but couldn't get a good seal with a gasket. The sealant worked fine for me.Keep smiling, it only hurts when you think it does!

I would have to agree, I also go one step further and take a center punch and a small hammer and install some dimmples on the block aswell as the intake so that the silicone has something to adhere to and help hold in place.
