The dreaded valve cover gasket leak makes a mess of your vehicle’s engine bay. Luckily, replacing it is a quick and easy DIY job that can be completed with a basic set of hand tools.



What is a Valve Cover Gasket?

The valve cover is typically the most visible part of the engine when you look under the hood. When removed, the cover allows access to the cylinder head’s components. Although the valve cover gasket can be reused many times, it can eventually wear out and become cracked, resulting in an oil leak coming from the top of the engine.

How does a Valve Cover Gasket Work?

The valve cover gasket creates a tight seal between the top of the engine’s cylinder head and its valve cover. On most engines, the valve cover gasket fits into a groove on the valve cover. The assembly is then placed atop the cylinder head and the fasteners are torqued. The gasket material expands out to form a tight seal.

How is a Valve Cover Gasket Made?

Most valve cover gaskets are mass-produced on heavy factory machinery out of flexible, molded rubber or plastic.

Valve cover gaskets often become tangled up if not handled carefully. Before installing a new gasket, you may want to use small dabs of RTV to secure it to the bottom of the valve cover. Otherwise the gasket may fall out of its grooves as you fit the valve cover to the cylinder head.

Why does the Valve Cover Gasket Fail?

  • Rubber and plastic parts, like valve cover gaskets, develop cracks and fail due to age and oxidation.
  • Valve cover leaks are common on many older vehicles.
  • Insufficient oil change frequency increases wear on the valve cover gasket.

What are the Symptoms of Valve Cover Gasket Failure?

  • The sudden appearance of a small oil leak traced to the top of the engine.
  • Oil may drip on the exhaust, causing blue or white smoke to appear through the vehicle’s hood and fender gaps.
  • Low oil reading during a regular oil check.

What are the Implications of Valve Cover Gasket Failure?

  • Leaking valve cover gaskets attract and spread dirt and dust in the engine bay, making maintenance and repair work on your vehicle more difficult.
  • Insufficient oil volume in the cylinder head may cause valvetrain damage.
  • Oil leaks damage driveways, roads, and parking lots.
