Camshaft replacement costs between $400 and $2,500 for most vehicles, depending on which camshaft needs replacing, whether the engine is in-line or V-shaped, and whether you do the work yourself or hire a mechanic.

The camshaft is a shaft inside your engine that opens and closes your intake and exhaust valves at precise moments. When one wears out or breaks, your engine runs poorly or not at all. The cost to fix it splits into two parts: the part itself and the labor to install it.

A new camshaft costs $150 to $900 depending on your vehicle's make and model. The labor to remove the old one and install the new one typically runs $250 to $1,600. A V-shaped engine (V6, V8) costs more than an in-line four-cylinder because the mechanic has to remove more parts to reach the camshaft. Some vehicles require removing the entire cylinder head, which adds hours of work.

Key Takeaways

  • Parts alone cost $150 to $900, and labor typically adds $250 to $1,600 depending on engine type and how many camshafts need replacing.
  • V-shaped engines cost significantly more than four-cylinder engines because the camshaft sits deeper in the engine and requires more disassembly.
  • A mechanic's hourly rate and your vehicle's age and model matter more than the camshaft itself — labor is usually the larger bill.
  • Getting a quote from your mechanic before authorizing work protects you from surprise costs, since some vehicles require additional repairs once the engine is open.

Why labor costs vary so much between vehicles

The position of the camshaft in your engine determines how much work a mechanic has to do to reach it. In a four-cylinder engine, the camshaft sits on top of the cylinder head and may be accessible by removing the valve cover — a job that takes one to two hours. In a V6 or V8, the camshaft sits lower, often requiring the mechanic to remove the cylinder head itself, which can take six to ten hours.

Some vehicles have multiple camshafts — one for intake valves and one for exhaust valves on each side of a V engine. If both need replacing, you pay for two parts and double the labor. Overhead cam engines (where the camshaft sits on top of the cylinder head) are cheaper to work on than cam-in-block engines (where it sits lower in the engine block), which are now rare but still appear in some trucks.

Your mechanic's hourly rate also matters. Independent shops typically charge $75 to $150 per hour, while dealerships charge $120 to $250 per hour. A job that takes eight hours at a dealership ($960 to $2,000 in labor alone) might cost $600 to $1,200 at an independent shop.

What's included in the total bill

When you get a quote, the mechanic should break down the cost into parts, labor, and any additional work discovered once the engine is open. The camshaft itself is straightforward, but the job often uncovers related problems.

Gaskets and seals around the cylinder head or valve cover dry out and crack when they're exposed during the repair. A mechanic may recommend replacing them while the engine is already apart, which adds $50 to $300. Timing chains or belts that synchronize the camshaft with the crankshaft sometimes need replacement at the same time, adding $200 to $800. If your vehicle has a timing belt (rather than a chain), the mechanic may recommend replacing it as preventive maintenance since they're already deep in the engine.

Oil and filter changes are often included in the final reassembly, and some shops charge a disposal fee for the old parts. Ask your mechanic to list everything separately so you understand what you're paying for.

Symptoms that signal a failing camshaft

A worn or broken camshaft usually produces clear warning signs before it fails completely. Your engine may run rough at idle, hesitate when you accelerate, or produce a ticking noise from the top of the engine. The check engine light often comes on, and a mechanic can read the code to confirm a camshaft problem.

If the camshaft breaks suddenly rather than wearing gradually, your engine may stall and refuse to start. This is less common but more urgent because the engine won't run at all until it's fixed. Either way, driving on a failing camshaft risks damaging other engine parts, so getting it inspected soon after symptoms appear usually keeps the repair bill lower.

Comparing repair shops and getting an accurate quote

Call three shops — your dealership, an independent mechanic, and a chain shop like Firestone or Midas — and ask each for a written estimate. Provide your vehicle's year, make, model, and current mileage. Tell them which symptoms you're experiencing so they can confirm the diagnosis before quoting.

A written estimate should include the part cost, labor hours and hourly rate, any additional repairs the mechanic recommends, and the total. Compare not just the price but the warranty: dealerships typically warranty their work for 12 months or 12,000 miles, while independent shops may offer 6 months or 6,000 miles. A lower price that comes with a shorter warranty may cost you more if something goes wrong.

Ask whether the quote includes a diagnostic fee. Some shops charge $50 to $150 to confirm the camshaft is actually the problem, and some credit that fee toward the repair if you proceed. Others include diagnostics in the repair cost. Clarifying this upfront prevents surprises.

Whether to replace the camshaft yourself

Replacing a camshaft yourself is possible if you have mechanical experience, the right tools, and a service manual for your vehicle. The part cost stays the same ($150 to $900), but you save the labor bill entirely. However, this job requires removing multiple engine components, working with precise timing, and reassembling everything correctly — mistakes can cause serious engine damage.

Most DIY mechanics attempt this work only on simpler engines like four-cylinder vehicles where the camshaft is more accessible. Even then, you'll need a camshaft removal tool (which you may have to rent or buy for $30 to $100), a torque wrench to tighten bolts to exact specifications, and several hours of uninterrupted time. If you're unsure about any step, stopping mid-repair and taking the vehicle to a shop costs more than paying for the full job from the start.

Frequently Asked Questions

How long does a camshaft replacement take?

A four-cylinder engine typically takes two to four hours. A V6 or V8 takes six to ten hours. Some vehicles require overnight work if the shop needs to order parts or if additional problems are found during disassembly. Ask your mechanic for an estimated timeline when you drop off the vehicle.

Can I drive my car with a bad camshaft?

You can drive short distances if the engine still runs, but the vehicle will run rough, use more fuel, and risk stalling. Continued driving risks damaging the timing chain, valves, or cylinder head. Have it inspected and repaired as soon as you notice symptoms.

Is a used or rebuilt camshaft cheaper than a new one?

Used camshafts cost $50 to $300 and rebuilt ones cost $100 to $500, both less than new parts. The tradeoff is that used parts carry no warranty and may fail again soon. Most mechanics recommend new parts for this repair because the labor cost is so high that replacing a failed used part means paying labor twice.

Will my warranty cover camshaft replacement?

Factory warranties typically cover camshaft failure for three years or 36,000 miles. Extended warranties vary — check your paperwork or call your warranty provider. If you're past the warranty period, the full cost is yours. Some credit card companies offer purchase protection that may cover repairs on vehicles bought with their card.

What's the difference between a timing chain and timing belt?

A timing chain is metal and lasts the life of the engine. A timing belt is rubber and typically needs replacement every 60,000 to 100,000 miles. If your vehicle has a timing belt, the mechanic may recommend replacing it during camshaft work since the engine is already open — this adds cost but prevents a separate repair later.
