What is a Head Gasket?
A head gasket is a sealing element between the engine and cylinder head. It is made of four or more sheets of metal that come together to create a tight fit, preventing oil and gas from leaking out of the engine. When the gasket starts to leak, it can cause decreased fuel efficiency, rough idle and even failure of the engine. Head gaskets are typically replaced when they start to leak, but there are other signs that indicate they need to be repaired.
Types of Head Gaskets
There are three types of head gaskets: pre-assembled, self-assembled, and fabricated.
Pre-assembled gaskets come fully assembled in the form of an O-ring and metal washer. To replace a pre-assembled gasket, remove the engine cover and locate the gasket. Unbolt the two nuts that secure it to the manifold andreplace it with a new one.
Self-assembling gaskets are similar to pre-assembled gaskets, but they don’t come with an O-ring. Instead, they have a metal washer that sits on top of an adhesive pad. When you replace a self-assembling gasket, you must first remove the adhesive pad by peeling it off in layers until it’s completely gone. Then, glue a new metal washer to the adhesive pad and reattach the engine cover.
Fabricated gaskets are made from either rubber or plastic materials and are secured to the engine by either bolts or screws. When you replace a fabricated gasket, you must first remove the existing bolts or screws and then replace them with new ones.
