Britpart Spark Plug Hole Gasket Valve Cover Seal

The Britpart spark plug hole gasket, also called a spark plug tube seal, spark plug well seal or valve cover seal, helps keep engine oil out of the spark plug wells. The rubber seal fits around the spark plug tube opening in the valve cover. It forms a tight barrier between the valve cover and the spark plug area.

Key Features:

• Seals the spark plug tube opening in the valve cover to help prevent oil seepage into the spark plug wells
• Rubber construction is intended to hold up to repeated engine heat cycles
• Helps protect spark plugs and ignition components from oil contamination
• Replacement part from Britpart, a supplier of aftermarket parts for Land Rover and other 4x4 vehicles

Rubber seals harden and shrink over time. When that happens, oil can leak past them, which can cause oil-fouled spark plugs and misfires. Replacing the seals whenever the valve cover is removed is a common way to keep the engine sealed and running well. Lubricating the seal with a little engine oil during installation helps it seat evenly.
