The primary function of the 4.6 valve cover gasket is to prevent oil from seeping into areas where it's not needed, such as the spark plugs or combustion chamber. This oil leakage not only reduces efficiency but can also lead to serious engine damage over time. It can contaminate the spark plugs, causing misfires, and if oil enters the combustion chamber, it can result in excessive smoke and potentially engine knocking.
Super Helix Seal
This tough, chemically inert polymer has a wide working scope as well as:
Slacken the alternator or dynamo adjuster and pivot bolts, push the unit inwards and ease off the drive belt. Remove the belt completely.
One of the main advantages of Iridium Spark Plug is its ability to generate a more powerful and consistent spark, leading to improved engine performance and increased fuel efficiencyBS
