Camshaft replacement typically runs between $800 and $2,500 for a single cam, depending on your vehicle's make, model, and engine type.

The total cost breaks into two parts: the part itself and the labor. A new camshaft costs anywhere from $200 to $800, but the real expense is labor — mechanics usually charge $600 to $1,700 in shop time because the job requires removing the cylinder head, timing belt or chain, and multiple other components to reach the cam. Some vehicles are harder to access than others, which is why a luxury sedan or high-performance engine can push the bill significantly higher than a standard four-cylinder.

The range also depends on whether you need one cam replaced or multiple cams (some engines have four or more), whether the timing chain or belt needs replacement at the same time, and whether your mechanic finds additional damage once the engine is open. A shop cannot always know what they will find until they start the work.

Key Takeaways

  • Labor makes up most of the cost because the mechanic must remove the cylinder head and timing components to reach the camshaft.
  • A single camshaft part costs $200 to $800, but total labor typically adds $600 to $1,700 depending on your vehicle type.
  • Luxury vehicles, high-performance engines, and overhead cam designs often cost more because they require more disassembly.
  • Getting a written estimate before work begins protects you from surprise charges if the mechanic discovers additional problems.

Why the cost varies so much between vehicles

A Honda Civic and a BMW 5 Series both have camshafts, but the labor to replace them is completely different. The Civic's engine is compact and relatively straightforward to access; a BMW's is more complex, with more components in the way. Luxury brands, turbocharged engines, and vehicles with dual overhead cams (meaning two camshafts per cylinder bank instead of one) all require more time to disassemble and reassemble.

Engine location matters too. A front-mounted engine is usually easier to work on than one mounted sideways or at an angle. Some vehicles require you to remove the engine partially or completely, which can double or triple the labor cost. A mechanic can tell you the specific labor hours for your vehicle by looking up the repair manual for your exact year, make, and model.

What's included in the labor charge

When a shop quotes you $1,200 in labor, that covers more than just swapping out the cam. The mechanic has to drain the oil, remove the valve cover, unbolt the timing belt or chain, remove the cylinder head, take out the old cam, install the new one, and then reverse every step. Each of these steps takes time and requires precision — if the timing is off by even one tooth on the timing gear, the engine will not run correctly.

Many shops also replace the timing belt or chain while they are in there, since they are already removing it and the parts are inexpensive compared to the labor. Some replace the valve cover gasket and other seals that are disturbed during the work. These add-ons are usually worth doing because you are already paying for most of the labor; doing them later means paying for that labor again.

When you might need more than one camshaft replaced

Some engines have four, six, or even eight camshafts — one or two per cylinder bank depending on the design. If only one is damaged, you might replace just that one. But if multiple cams are worn or broken, or if the damage was caused by a timing chain failure that affected several components, you could be replacing two, three, or more at once. The labor cost does not double for each additional cam, because much of the disassembly is already done, but the parts cost does add up.

Ask your mechanic whether they recommend replacing all the cams or just the damaged one. Sometimes replacing only the bad cam leaves you with a mismatch in wear patterns that causes problems later. Other times, replacing just the one that failed is the right call. The mechanic's recommendation should be based on what they see when they inspect the engine.

Signs your camshaft might be failing

A failing cam usually announces itself through the check engine light, rough idle, or a ticking noise from the top of the engine. Some vehicles throw a specific code like P0014 or P0016 (cam timing codes). Others straightforward run poorly because the cam is not opening and closing the valves at the right time. If you hear a loud ticking that gets worse when you accelerate, that is often a sign the cam lobe is worn down and the valve lifter is hitting metal instead of the smooth cam surface.

The only way to know for certain is to have a mechanic pull the valve cover and look at the cam directly. If it is visibly pitted, scored, or flattened in spots, it needs replacement. If it looks fine but the timing is off, the problem might be the timing chain, a sensor, or something else — which is why diagnosis comes before the repair quote.

Getting an estimate and what to ask for

Call three shops and ask for a written estimate that includes the part cost, labor hours, and any additional work they recommend (timing belt, gaskets, seals). A good estimate will also tell you the total time the car will be in the shop — usually one to three days depending on how busy they are and whether they find surprises.

Ask whether the estimate is firm or if it could change once they start the work. Most shops will give you a firm estimate for the cam and labor, but reserve the right to add charges if they discover a broken bolt, a cracked head, or other damage once the engine is open. Ask them to call you before doing any work beyond what is in the estimate. This protects you from a $500 surprise charge for a broken bolt you did not authorize them to fix.

Also ask whether they are using a new OEM (original equipment manufacturer) part, a remanufactured part, or an aftermarket part. OEM parts are most expensive but carry a warranty. Remanufactured parts are cheaper and usually reliable. Aftermarket parts are the cheapest but vary in quality. Your mechanic can recommend which is appropriate for your vehicle.

Timing chain or belt replacement at the same time

If your vehicle uses a timing belt (rubber with teeth), it often needs replacement around the same time a cam fails, especially if the cam failure was caused by belt wear or breakage. A timing belt replacement alone costs $500 to $1,500 depending on the vehicle. If you are already paying $1,200 for cam labor, adding a belt replacement might only add $200 to $400 in parts and a few hours of labor — much cheaper than paying for the full labor again later.

If your vehicle uses a timing chain (metal), it lasts much longer and usually does not need replacement unless it has stretched or broken. A mechanic can inspect it while they are in there and tell you whether it should be replaced now or left alone. Replacing a timing chain costs more than a belt but is less common.

Frequently Asked Questions

Can I drive with a bad camshaft?

You can drive a short distance, but the engine will run rough, use more fuel, and may overheat or stall. Continuing to drive on a severely damaged cam risks damaging the cylinder head or other engine parts. If the check engine light is on and a mechanic has confirmed it is a cam problem, have it repaired within a few days rather than weeks.

Is a remanufactured camshaft as good as a new one?

A quality remanufactured cam is reliable and comes with a warranty, usually 12 months or 12,000 miles. The main difference is price — remanufactured parts cost 30 to 50 percent less than new OEM parts. Ask your mechanic which brands they trust and whether they have had problems with remanufactured cams in the past.

How long does a camshaft replacement take?

The actual work takes 8 to 16 hours depending on the vehicle, but the car is usually in the shop for one to three days because the mechanic may have other jobs scheduled. Some shops can turn it around in one day if they start early and work straight through. Ask when you call for the estimate.

Will replacing the camshaft fix my check engine light?

If the code is specifically a cam timing or cam sensor code, yes — replacing the cam or repairing the timing should clear it. If the code is something else that just happened to appear at the same time, the light may stay on. The mechanic should clear the code after the repair and test-drive the vehicle to confirm it does not come back.

What if the mechanic finds a cracked cylinder head?

A cracked head discovered during cam replacement can add $1,500 to $3,000 to your bill, depending on whether it can be repaired or must be replaced. This is why you ask the shop to call before authorizing any work beyond the estimate. You can then decide whether to proceed, get a second opinion, or stop the work and pick up the vehicle.
