How much does it cost to replace a valve cover?
The cost to replace a valve cover can vary significantly depending on the make and model of your vehicle, as well as the specific parts and labor required. On average, you can expect to pay between $200 and $500 to have a valve cover replaced by a professional mechanic.
What is a Valve Cover?
A valve cover is a protective metal or plastic cover that sits atop the engine cylinder head, enclosing the valve train components such as the rocker arms, pushrods, and valve springs. Its primary function is to keep oil contained within the engine and prevent dirt and debris from entering the critical valve train area.
Reasons for Valve Cover Replacement
- Cracked or damaged valve cover: Over time, the valve cover can develop cracks or other damage, leading to oil leaks and potential engine damage.
- Worn gasket: The valve cover gasket, which seals the cover to the cylinder head, can deteriorate and cause oil leaks.
- Routine maintenance: Some manufacturers recommend replacing the valve cover as part of regular engine maintenance, typically every 60,000 to 100,000 miles.
Replacing a valve cover is generally a straightforward repair, but the cost can vary depending on the specific vehicle and the complexity of the job.
Factors Affecting Valve Cover Replacement Cost
- Parts cost: The valve cover itself can range from $50 to $200 or more, depending on the make and model of the vehicle.
- Labor cost: The labor to replace the valve cover can range from $100 to $300 or more, depending on the difficulty of the job and the mechanic's hourly rate.
- Additional components: In some cases, additional parts such as the valve cover gasket, spark plug tubes, or other related components may need to be replaced, adding to the overall cost.
It's important to note that the cost can also vary depending on the location and the specific mechanic or repair shop you choose to perform the work.
Is it expensive to replace a valve cover?
The total cost for a valve cover replacement typically ranges from $250 to $800, with the price depending on the vehicle's make and model, labor rates, and whether just the gasket or the entire cover needs replacing. Parts alone can cost between $100 and $400+ for the cover itself, while labor can add another $50 to $300 or more depending on engine accessibility and complexity.

Cost breakdown
- Valve cover: $25 to over $700, depending on material, brand, and vehicle.
- Gasket set: $20 to $80.
- Bolt grommets/seals: $10 to $40.
- Labor: Can be 1 to 3 hours or more, depending on the engine type and accessibility. For a four-cylinder, it might take 1–2 hours, while a V6 or V8 can take 1.5–3 hours per bank.
- Other parts: $5 to $15 for RTV/FIPG (if specified) and potentially shop supplies.
Factors that influence the cost
- Vehicle make and model: Some cars, particularly luxury or performance models, can be much more expensive due to parts and labor complexity.
- Gasket vs. cover replacement: Replacing just the gasket is cheaper than replacing the entire valve cover, which is often necessary if the cover itself is warped.
- Labor rates: Shop and location-specific labor rates will affect the final price.
- Labor time: The difficulty of accessing the valve cover on your specific engine will directly impact the labor cost.
- Parts quality: Opting for OEM (Original Equipment Manufacturer) parts can be more expensive but may save you a headache in the long run if aftermarket parts fit poorly.
- Additional repairs: Mechanics may recommend replacing other parts, like spark plugs, during the service, which will increase the total cost.
How severe is a valve cover leak?
Engine misfires: A valve cover gasket leak can allow oil to enter the spark plug wells, which can cause misfires and a rough-running engine. Reduced engine performance: If the leak is severe, the engine may lose some performance due to the loss of oil pressure.
Is it worth fixing a valve cover gasket?
A faulty valve cover gasket is not a problem that will leave a vehicle stranded at the roadside. However, at the same time, you can't afford to ignore it for long. After a few dozen miles, the fault will begin to damage the engine and your maintenance costs will rise.
Can I drive with a bad valve cover?
Yes you can. There's no oil pressure inside the valve covers, only splash. Someone might have to add oil to make up for loss, and it can get messy. But driving with a leaking valve cover isn't harmful to the motor.
