How Much Does It Cost to Replace a Camshaft?

Camshaft replacement is one of the more serious — and expensive — engine repairs a vehicle can need. Understanding what drives the cost helps you evaluate quotes, ask the right questions, and decide how to move forward.

What a Camshaft Does

The camshaft is a rotating shaft inside your engine that controls the opening and closing of the intake and exhaust valves. As it spins, lobes along the shaft push against valve components in precise sequence, timed to the movement of the pistons. This timing is what allows the engine to draw in air and fuel, ignite it, and push exhaust gases out — in the right order, at the right moment.

Most modern engines have two camshafts (one for intake valves, one for exhaust) in a dual overhead cam (DOHC) configuration. Older or simpler engines may use a single overhead cam (SOHC) or a pushrod design, where the camshaft sits inside the engine block rather than on top of the cylinder head.

Why Camshafts Fail

Camshaft damage is almost always tied to lubrication problems. The shaft and its lobes rely on a steady supply of clean oil to function. When oil is dirty, low, or delayed in reaching the camshaft — common in engines with variable valve timing (VVT) systems — the lobes wear down or score. Other causes include:

• Timing chain or belt failure that causes the cam to jump timing
• Debris in the oil from a spun bearing or other internal failure
• Manufacturing defects (more common in certain model years or engine families)
• Extended intervals between oil changes

In some cases, only the camshaft followers, lash adjusters, or lifters are worn — not the cam itself. A thorough diagnosis is needed to confirm exactly what's failed before parts are ordered.

Typical Camshaft Replacement Costs

Costs vary widely based on the engine, vehicle type, and labor market in your area. That said, here's a general picture of what most drivers encounter:

These are general estimates. Luxury vehicles, performance engines, and models with complex DOHC or VVT systems often fall at the higher end — or above it. Domestic V8 pushrod engines are typically on the lower end for parts, though labor is still significant because of how much has to come apart.

What Drives the Price Up (or Down)

Engine design is the biggest variable. An overhead cam engine requires removing the cylinder head or at minimum the valve cover and timing components. This is intensive, skilled work. A pushrod engine's camshaft sits deeper in the block, which means more disassembly — but the parts themselves are often cheaper and more standardized.

Number of camshafts matters too. A DOHC V6 or V8 has four camshafts. If all four are worn, parts and labor multiply accordingly.

Variable valve timing components add complexity. Many modern engines use oil-pressure-controlled VVT actuators (sometimes called phasers) that attach to the camshaft. If the cam is damaged, these often need replacement too — and they're not cheap.

OEM vs. aftermarket parts is another fork in the road. Original equipment parts from the manufacturer cost more but are built to exact spec. Quality aftermarket camshafts from reputable suppliers can be a reasonable alternative, especially for older vehicles. Cheap, no-name parts carry more risk in a high-stress application like this.

Labor rates by region shift costs significantly. Shops in major metro areas often charge $150–$200 per hour. Smaller markets may run $90–$130. A repair that takes 8–12 hours of labor will feel that difference immediately.

Additional repairs almost always accompany a cam replacement. Shops typically recommend replacing related wear items at the same time — timing chain or belt, tensioners, guides, oil control valves, and seals — since the engine is already partially disassembled. Skipping these can mean returning for another major teardown sooner than expected.

🔧 Pushrod vs. Overhead Cam: A Meaningful Cost Difference

Pushrod engines (common in older American V8s and many truck engines) tend to have lower parts costs, but still require significant labor. Overhead cam engines — the standard in most modern cars — require more disassembly around the top of the engine. Either way, this isn't a quick job. Plan for at least a full day in the shop, often more.

Should You Replace the Engine Instead?

When the cost to replace a camshaft approaches or exceeds the vehicle's market value, some owners consider a used or remanufactured engine as an alternative. A used engine with lower miles sometimes costs less than a full cam replacement, particularly if other internal damage is present. That calculation depends entirely on the vehicle's age, mileage, value, and what else the mechanic finds during teardown.

The Missing Pieces

What you'll actually pay depends on your specific engine configuration, your vehicle's age and condition, your region's labor rates, whether related components also need replacement, and what a hands-on inspection reveals. Two vehicles with the same symptom can leave the shop with bills that differ by thousands of dollars. Getting a written estimate — and understanding what's included in it — is the clearest path forward.
