Fel Pro Gaskets

A felpro head gasket is a gasket that is located between the engine block and cylinder head for a internal combustion engine. A fel pro head gasket seals the cylinders to ensure maximum compression and avoid leaks of coolant or oil into the cylinders.
Head Gasket Types
These typically gasket consist of three layers of steel. The contact faces are usually coated with a rubber-like coating such as Viton that adheres to the cylinder block and cylinder head.
Solid copper -- A solid sheet of copper, copper gaskets are extremely durable.
Composite -- these are made from asbestos or graphite and are more prone to blowouts. Asbestos gaskets are rare due to health concerns.
Gasket Problems
Occasionally, the compression in the cylinder will cause a leak to form in the gasket and the gasket will have to be replaced, I would use a felpro head gasket or a gasket set. The use of aluminum rather than iron cylinder heads makes this problem more prominent but aluminum has a much greater thermal expansion, which causes more stress on the head gasket. Engine makers have reduced this problem by adding Teflon to the surface of the head gasket.
If the gasket fails, problems will, from compression loss, to exhaust gases being exposed to the cooling system and causing the engine to overheat. I had this problem with one of my cars and how I found the problem was my motor oil was white. This is a sign that antifreeze is mixing with the oil. Coolant can also end up in the cylinders causing steam that can damage your exhaust.
A damaged head gasket can cause leaks between cylinders so use a pressure gauge, or do a leak-down test, to see what your compression loss is. Driving with a blown head gasket can cause extensive damage from overheating and loss of oil. Burning oil is usually Blue exhaust smoke.
