Buyer's Guide to Nissan Cylinder Heads and Valve Cover Gaskets

All About Nissan Cylinder Heads

The cylinder head is essentially a housing -- made of either aluminum or cast iron -- that sits atop your engine block. It helps to draw air into your engine while discharging exhaust gases. It also channels coolant into the engine block to help maintain an ideal running temperature. Finally, with the help of a head gasket, the cylinder head helps to prevent water and oil from leeching into the combustion chamber.

All About Nissan Valve Cover Gaskets

Valve cover gaskets seal the space between the valve covers and the cylinder heads, containing the motor oil that's essential to smooth engine operation. Most are made of stamped metal, molded plastic, or cast metal, providing a solid surface that redirects any splashing motor oil back into the engine's head and passageways.

• Engine misfires
• Reduced engine performance
