What kind of gasket do I need for intake manifold?
What kind of gasket do I need for intake manifold?
Most Fel-Pro ® Performance intake manifold gaskets are designed without a metal core, to allow engine builders to trim the gasket for exact fit on modified ports. The base gasket material resists coolant, gasoline, alcohol and oil.
What causes coolant to leak from intake manifold?
The coolant leaks on these engines are the result of a combination of factors: heat, thermal cycling, coolant neglect, corrosion and degradation of the OEM gasket. Some have blamed the coolant leak problem on the type of plastic used in the OEM gaskets.
What kind of engine has high intake gasket failure rates?
Engines that have had high intake gasket failure rates include 1990 to 2005 Buick, Chevrolet, Oldsmobile and Pontiac 3.1L, 3.4L, 3.8L and 4.3L V6 engines, and 1996 to 2002 Chevy 5.4L and 5.7L V8 engines. These applications alone represent a potential replacement market of more than 10 million vehicles.
What causes air leak in Chevy 8.1L Vortec?
One other potential issue worth point out: sometimes the manifold itself can be the cause of an air leak. The manifold on the 8.1 is made of plastic (as most are) and over time the plastic can warp and crack from the constant heat it’s exposed to.

What kind of gaskets do I need for intake manifold?
Back in the days when most engines had cast iron blocks, heads and manifolds, the intake manifold could be easily sealed with simple and relatively inexpensive die cut fiber faced metal gaskets (solid or perforated core). Sealer was usually required to ensure a leak-free installation.
