If you have a struggling engine and are considering a camshaft repair or replacement project, you probably have lots of questions. And for good reason. A camshaft and related components can be expensive and time consuming to replace, so it’s well worth a bit of research before your roll up your sleeves or ship your vehicle off to a shop.
How much will this end up costing? How big of a job is this going to turn out to be? If I bother, what else should I replace while I’m in there? The honest answers to these questions depend on the details, so they can’t only be answered properly without a detailed inspection, but we can break down some of the main factors that will apply, no matter what kind of engine you have.
Whether you’re working on a heavy-duty diesel model or a smaller engine, understanding camshaft replacement costs can help you figure out when it’s worth it and when it’s not.

What Does It Cost to Replace a Camshaft?
As industries focus on sustainability and performance, the demand for high-quality camshafts continues to grow. With the global automotive industry projected to grow at a CAGR of 3.5% by 2030 (source), the market for camshafts across all sectors is poised for sustained expansion. The camshaft replacement cost can vary depending on engine type, accessibility, labor rates, and whether you’re replacing related components. For heavy-duty diesel engines, total replacement cost can range from $1,500 to over $4,000 CAD, depending on the complexity of the job.
Here’s a rough breakdown:
- Parts: A new camshaft typically costs $500–$1,500, but the price can jump significantly for specialty or OEM parts.
- Labour Costs: These range from $800 to $2,500, depending on engine layout and how much teardown is needed.
- Other Components: If you’re also replacing timing components, gaskets, and possibly the camshaft position sensor, expect the total to climb.
What Else Should You Replace When Replacing a Camshaft?
Good question!. When you replace a camshaft, it’s typically wise to also replace:
- Timing chain or timing belt and related tensioners
- Camshaft and crankshaft seals
- Lifters and pushrods, if applicable
- Gaskets between the cylinder head and valvetrain covers
- The camshaft position sensor, especially if it’s contributing to engine light warnings
Replacing just the camshaft without addressing these parts can lead to premature wear, leaks, or continued engine performance issues.
Is Camshaft Replacement a Big Job?
Yes—it absolutely is. The camshaft sits at the heart of your engine system, managing the opening and closing of intake and exhaust valves with precision timing. Reaching it often requires partial or full engine disassembly, depending on your setup. For example, in overhead cam engines, you’ll likely be pulling the timing belt or timing chain, valve covers, and possibly even the cylinder head.
That’s why labor costs account for such a large portion of the bill.
What Are the Signs of a Failing Camshaft?
A bad camshaft can cause all sorts of trouble:
- Misfiring or rough idle
- Decreased fuel efficiency
- Power loss or engine damage
- Clicking or ticking noises from the engine
- Check engine light triggered by a faulty camshaft sensor
In some cases, a broken camshaft can even lead to severe engine damage, especially if it disrupts valve timing and causes piston interference.
Is It Worth It to Replace a Camshaft?
If the rest of the engine is in solid condition, absolutely. A properly installed new camshaft can restore normal operation, unlock performance benefits, and extend engine life. However, if you’re dealing with widespread engine parts wear or significant mileage, it might be time to evaluate the full rebuild cost or a remanufactured engine option.
Finding the Right Camshaft and Getting It Done Right
Camshaft failure isn’t something to ignore, but it’s also not something to rush. Whether you’re chasing down a nagging engine light or dealing with a failing camshaft in a workhorse diesel, the key is to choose high-quality replacement parts.
