The Cost of Getting A Valve Job

Doing a valve job on a car can be an expensive undertaking. In fact, it can cost anywhere from around $750 to upwards of $1500 – depending on the make and model of the vehicle. But what is a valve job and why is it so expensive?

What is a Valve Job?

A valve job is a process performed by automotive mechanics which involves grinding down or replacing the valve seats and valve faces in a car’s engine block. This will improve the car’s performance and fuel efficiency. A valve job is usually performed when an engine is beginning to show signs of poor performance, such as loss of power, misfiring or low compression.

Why is a Valve Job So Expensive?

There are a few different reasons why a valve job can cost so much.

  • Labor Costs – Performing a valve job involves a great deal of labor and precision. Automotive mechanics will carefully remove the cylinder head from the engine block, inspect and measure the valves and seats and make sure the surfaces are smooth and free of debris before they can reassemble the engine. This can involve a great deal of time and effort, which translates into higher labor costs.
  • Parts & Materials – Depending on the make and model of the vehicle, a mechanic may need to make use of specialty tools and parts. This can drastically increase the cost of doing a valve job.
  • Machine Shop Work – In some cases, the valves and seats may need to be replaced entirely. This may require the use of a machine shop, which can add to the cost significantly.

What Else Can I Do?

If the cost of doing a valve job is too high for you, there are a few other things you can do to keep your engine running well. If the engine is running rough, changing the spark plugs and spark plug wires can help to make the engine run smoother. You can also do a heavy-duty oil treatment, which helps to clean the engine and restore power.

In the end, it’s important to remember that a valve job is a more substantial repair than just changing the oil or spark plugs, so it can be an expensive undertaking. But if your car is beginning to show signs of poor performance, it may be worth considering.
