Camshaft replacement typically costs between $800 and $2,500 for a single camshaft, or $1,500 to $4,000 if both need replacing, depending on your vehicle's make, model, and engine type

The total bill breaks into two parts: the part itself and the labor. A camshaft alone usually runs $300 to $1,000, but the work to remove and install it is often the larger expense. Mechanics charge $500 to $2,000 in labor, sometimes more, because reaching the camshaft means taking apart the top of your engine — removing the valve cover, timing belt or chain, and other components that sit in the way.

The exact price depends on whether your engine has one camshaft or two, how accessible it is, and whether your mechanic finds other problems while the engine is open. Some vehicles are straightforward; others require removing the entire cylinder head, which doubles the work.

Key Takeaways

  • Parts cost $300 to $1,000 per camshaft; labor typically runs $500 to $2,000 depending on how deep the mechanic must dig into your engine.
  • Vehicles with two camshafts (one for intake valves, one for exhaust) cost more than those with one, and dual overhead cam engines are more expensive to work on than single overhead cam engines.
  • Independent mechanics often charge less than dealerships for the same work, though dealership parts may carry a longer warranty.
  • While the camshaft is being replaced, your mechanic may recommend replacing the timing belt, valve cover gasket, or spark plugs if those parts are already exposed and wearing out.

Why labor costs so much more than the part itself

A camshaft sits at the top of your engine and controls when your valves open and close. To reach it, a mechanic must remove the valve cover (a metal plate bolted to the top), then unbolt the timing belt or chain that synchronizes the camshaft with the crankshaft. On some vehicles, the entire cylinder head comes off. This is not a 30-minute job.

The labor time varies widely. A straightforward single-cam engine might take 3 to 5 hours. A dual overhead cam engine with the cylinder head removal can take 8 to 12 hours or longer. At $100 to $200 per hour (the typical shop rate), you can see how labor becomes the dominant cost.

Once the camshaft is out, the mechanic inspects the timing chain or belt, the valve lifters, and the gaskets. If any of these are worn, replacing them now — while everything is already apart — costs far less than paying for another repair later.

Single cam versus dual cam engines

A single overhead cam (SOHC) engine has one camshaft that operates both the intake and exhaust valves. Replacing it is usually the cheaper option, typically $800 to $1,500 total.

A dual overhead cam (DOHC) engine has two camshafts — one for intake, one for exhaust. If both need replacement, you are paying for two parts and the labor is often the same (since the mechanic is already deep in the engine), so the total might be $1,500 to $2,500. If only one camshaft is damaged, the cost is closer to $1,000 to $1,800.

Some vehicles have four camshafts (two per cylinder bank on V6 or V8 engines). These are rare in smaller cars but common in larger trucks and performance vehicles. Replacement costs scale accordingly and can exceed $3,000 to $4,000.

Dealership versus independent mechanic pricing

Dealerships typically charge $150 to $250 per hour in labor, while independent shops charge $75 to $150. For an 8-hour job, that difference adds up to $600 to $1,200 in labor alone. Parts prices are often similar, though dealerships may charge a markup.

The trade-off is warranty and familiarity with your specific vehicle. A dealership mechanic works on your make and model every day and has factory service bulletins that flag common problems. An independent shop may be faster and cheaper but may not catch vehicle-specific issues.

If your vehicle is still under warranty, check whether the dealership will cover the camshaft replacement. Some warranties cover defective camshafts but not wear-related failure. Knowing this before you get a quote can save you from an unwelcome surprise.

Additional costs that often appear during the job

Once the valve cover comes off, your mechanic can see the condition of parts that are difficult to inspect otherwise. They may recommend replacing the timing belt (if your engine has one rather than a chain) because it is already exposed and often wears out around the same time as a camshaft. A timing belt replacement adds $300 to $800.

The valve cover gasket — the seal between the valve cover and the engine block — often leaks after being removed and reinstalled. Replacing it at the same time costs $100 to $300 and prevents an oil leak later. Spark plugs are also straightforward to replace while the valve cover is off, adding $50 to $150.

Your mechanic should give you a written estimate that lists the camshaft replacement separately from these add-ons. Ask which items are necessary for the repair and which are preventive. This helps you decide what to authorize before the work begins.

Signs your camshaft may need replacement

A failing camshaft usually produces a ticking or tapping noise from the top of the engine, especially when you start the car cold. You might also see a check engine light, rough idling, or a loss of power. Some vehicles with variable valve timing systems show a code related to camshaft position.

Camshaft failure is not always sudden. A worn camshaft can run for months with symptoms before it fails completely. If you hear the noise and your mechanic confirms it is camshaft-related, getting it replaced sooner rather than later prevents damage to other engine parts and keeps repair costs from climbing.

Getting an accurate quote before committing

Call or visit at least two shops — one dealership and one independent mechanic — and describe the symptoms. Provide your vehicle's year, make, model, and engine size. A good shop will give you a written estimate that breaks down parts, labor hours, and any recommended add-ons.

Ask whether the estimate includes a warranty on the work. Most shops offer 12 months or 12,000 miles on labor. Some offer longer warranties on parts. A warranty protects you if something goes wrong shortly after the repair.

Do not choose based on price alone. A shop that quotes significantly lower than others may be cutting corners or underestimating the work. A quote that is significantly higher may include unnecessary add-ons. The middle estimate from a shop with good reviews is usually the safest choice.

Frequently Asked Questions

Can I drive my car if the camshaft is failing?

You can drive it short distances, but a severely worn camshaft can damage the cylinder head or valve train if it fails completely. If your mechanic has confirmed the problem, schedule the repair within a few days rather than weeks. Continuing to drive risks a breakdown that leaves you stranded or causes more expensive damage.

Is camshaft replacement covered by my car's warranty?

Most factory warranties cover defective camshafts for 3 to 5 years or 36,000 to 60,000 miles. Wear-related failure after that is your responsibility. Check your warranty paperwork or call your dealership to confirm coverage before paying out of pocket.

Why does one camshaft fail but not the other?

A single camshaft can wear unevenly if the oil is dirty, the valve lifters are worn, or the timing chain is loose. If only one camshaft is damaged, the mechanic will inspect the other and the surrounding parts to understand why. Sometimes both need replacement even if only one shows obvious wear.

Should I replace the timing belt while the mechanic is already in there?

If your timing belt is within 20,000 miles of its recommended replacement interval, yes — it costs far less to do it now than to pay for another major repair when it fails later. If it was recently replaced, you can skip it. Ask your mechanic to show you the belt's condition and the manufacturer's replacement schedule for your vehicle.

What is the difference between a camshaft and a crankshaft?

A camshaft controls when valves open and close. A crankshaft converts the up-and-down motion of the pistons into rotational motion that turns the wheels. They work together but are separate parts. Crankshaft replacement is much more expensive because it requires removing the entire engine.
