What is the main purpose of valve seals?

Valve seals are essential for preventing engine oil from leaking past the valve guides and into the combustion chamber. This helps reduce oil consumption, prevent smoke from the exhaust, and keep your spark plugs clean.

Do these seals fit all valve stem sizes?

No, these specific COMP Cams 504-12 seals are designed for 3/8-inch valve stems. COMP Cams offers other valve seals in different sizes and styles for various applications.

What type of spring setup are these seals best suited for?

These umbrella-style seals are typically used when a larger-than-stock diameter spring is installed, such as in a double spring configuration. COMP Cams offers other seal types for single or triple spring setups.

Product Details

COMP Cams is well-known for performance engine components, and their valve seals are no exception. These 504-12 Umbrella Valve Seals are designed to keep unwanted oil from entering your engine's combustion chamber through the valve guides. This is crucial for maintaining engine health and performance, preventing issues like excessive smoke and fouled spark plugs.

These umbrella seals are a solid option for stock valve guide applications with 3/8-inch valve stems. They typically don't require any machine work to install, making them a straightforward replacement part. While COMP Cams offers various seal types for different spring setups, these umbrella seals are a good choice when you're using a larger-than-stock diameter spring, such as in a double spring configuration.

This set includes 12 seals, enough for most typical 6-cylinder engines. They fit a wide range of American Motors, Chrysler, and Dodge vehicles from the 1960s through the 1980s, making them a versatile choice for many classic builds.
