engine gasket replace

Composite and silicone gaskets seal metal-to-metal surfaces in today's engines. Plenums, carburetors, head covers, valve covers, exhaust systems and oil pans all use gaskets to match surfaces perfectly, control air and fluid pressure and to prevent leaks. Composite gaskets are just that—a variety of materials (cork, paper, rubber, felt) combined together and designed for specific applications. A gasket sealant or adhesive usually aids their assembly and function. Silicone (or formed-in-place) gaskets are created from a special compound that is applied directly to the parts in question and is allowed to cure in place.


Today's engines run at high rpm and at high temperatures. They are often constructed of various alloys that expand at different temperatures and rates as heat builds. And most modern engines use computer controls that are extremely sensitive and prone to misbehavior should they sniff some unfamiliar compound in their midst. For all these reasons and more, make sure that gasket and sealant compounds are designed for your vehicle, engine and application.


Please read these guidelines through before proceeding. Vehicle and service manuals should also be at hand.

Stay Safe
Appropriate maintenance and service procedures will keep your car in the pink and you out of the emergency room. So whenever you're working on your vehicle, please do the following:


> Keep a first-aid kit nearby.
