Thread: SBC intake gaskets?

Tweet

If you see one taped over, it is to keep sealant out of the hole while they are installing the intake manifold. If you have a plug in yours, it means that someone used a plug rather than tape to keep foreign debris out of the hole while they installed the intake manifold. You can screw in an electric sender for an electric oil pressure gauge or you can screw in an adapter that will allow the use of a nylon or copper line to feed to a mechanical oil pressure gauge. My best advice is to use an electric gauge if you are going to mount the gauge inside the vehicle. If you want to run a mechanical, mount it on the cowl in front of the windshield, like some of the 60's and 70's cars. That way, if the gauge or line ruptures, you won't have hot engine oil spraying into the driver's compartment and maybe into your face.
