Best Price for Valve Cover Gasket Replacement

What is a Valve Cover Gasket and How Does It Work?

A valve cover gasket is a crucial component in your car’s engine that prevents engine oil from leaking between the valve cover and the cylinder head. The valve cover, usually made of aluminum or plastic, is bolted to the cylinder head, and the gasket forms a secure seal to keep the oil in place. Over time, heat can cause the gasket to weaken, or the bolts may loosen, leading to oil leaks.

Is It Safe to Drive with a Faulty Valve Cover Gasket?

It is generally safe to drive with a minor valve cover gasket leak, as long as the oil loss is minimal and the leak does not drip onto hot engine components, like the exhaust manifold. However, if you notice oil pooling beneath your car after parking, the leak is likely more serious, and you should address it promptly. A leaking gasket means you’re losing engine oil, so regularly check your oil levels to avoid running low and potentially damaging the engine.

When Should You Replace the Valve Cover Gasket?

Common signs of a faulty valve cover gasket include:

• Oil seepage or dripping: Oil leaking around the valve cover joint, often collecting on the valve cover or cylinder head, with dirt sticking to the oil.
• Oil inside the spark plug wells: If the spark plug tube seals fail, oil may pool in the wells, risking spark plug and wire damage.
• Oil leaks at rubber grommets: If the rubber grommets under the valve cover bolts are leaking, oil may seep around the bolt heads.

If you observe any of these signs, it’s likely time to replace the valve cover gasket to prevent further engine damage.

How Does Novo Repairs Replace a Valve Cover Gasket?

With Novo Repairs, you can enjoy a professional valve cover gasket replacement at home. Here’s the general process:

1. Remove the engine cover: If there’s a plastic cover, it must be taken off to access the valve cover.
2. Remove components: For 4-cylinder engines, electrical components and emission control tubing are removed. On 6- or 8-cylinder engines, more parts like the air intake plenum may need to be removed.
3. Remove the valve cover: After removing the retaining bolts, the valve cover is lifted off, and the sealing surface is inspected for warping.
4. Install a new gasket: The new valve cover gasket is placed, along with fresh rubber grommets for the bolts. Spark plug tube seals are replaced if necessary, and RTV sealant may be used for added sealing.
5. Reassemble the engine: The valve cover is reattached, components are restored, and bolts are tightened to the proper torque.
6. Check for leaks: The engine is started and visually inspected for any remaining leaks.

How Long Does a Valve Cover Gasket Last?

A valve cover gasket typically lasts 20,000 to 50,000 miles, depending on driving conditions, engine type, and maintenance. Regular inspections and prompt maintenance can help extend the gasket's life and prevent oil leaks that could lead to more serious engine issues.
