Intake Manifold Gasket Question

Over the holidays (Christmas) I will be installing new intake gaskets on my 67 convertible and I need some advice. I want to use Mr. Gasket Ultra-Seal and I need to know if I should use any sealer around the ports. I will be using black RTV on the end rails instead of the gaskets. Any advice would be appreciated.

Re: Intake Manifold Gasket Question

You don't really need any sealant around the ports. However, a very thin film of the RTV can't hurt. On our race cars we used to coat the entire gasket with a thin layer of RTV only so we could re-use the gasket. The thin layer made it not stick to the head or manifold and tear. Having said all that, have you checked for warpage with a straight edge?

Re: Intake Manifold Gasket Question

Just use a little bit of some good quality rtv around the water ports, I prefer Ultra Black myself. You can also use just a dab of yellow weatherstrip adhesive just to hold the side gaskets form slipping, usually the size of a match on the side of the outer intake ports.
The intake gasket sets are embrossed with a raised section around the ports so no sealer is required unless you have some gasket surface imperfections.
The weatherstrip adhesive is nasty ( we used to call it Yellow Death ), Good Luck getting the gaskets off if you use too much, you will be cursing and scraping for hours. JMO.

From what I've been told by some old school guys is NOT to use RTV around the intake ports because it has a chance of getting into the intake ports and could ruin the engine. I don't know if it's true or not but if I use anything it's Gasgacinch by Edelbrock.

I use Ultra Copper Sealer from Permatex and have not experienced any negative effects from using it around the ports.

Re: Intake Manifold Gasket Question

Old school here, wether its an embossed gasket, they're okay, or paper gasket, I likey, I have yet had a problem by not using any sealant/RTV on the ports across the head interface.

I do use about a good 1/4 inch diameter bead for the manifold-to-block interface as I have found the rubber seals do not flatten enough and cause port leakage.

As said, don't use yellow hel*, 3M Weatherstrip adhesive, you will need a jack hammer to separate later in life.

Re: Intake Manifold Gasket Question

Use intake sized bolts with the heads cut off on the corners to hold the gaskets in place. Makes for an easy installation of the manifold without slipping the gasket.
