But there are also mechanical reasons why camshafts fail: roller rockers can seize or lifters can damage camshaft lobes. The camshaft can spin out of time due to failed belts, gears, sheared pins or keys, or stretched\/failed chains and chain hardware, as well as problems with cam phasers used for variable cam timing.<\/p>\n\n\n\n<p>To help you determine when this part might be bad, we&rsquo;ve listed down the common signs of a bad camshaft.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6 Symptoms of a Bad Camshaft<\/h2>\n\n\n\n<p>When ignored, a busted camshaft may also cause extensive damage to some parts of the engine like the <a href=\"https:\/\/www.carparts.com\/crankshaft\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"crankshaft\">crankshaft<\/a> and <a href=\"https:\/\/www.carparts.com\/cylinder-head\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"cylinder head\">cylinder head<\/a>.<\/p>\n\n\n\n<p>To help you prevent all of this, here are common camshaft wear symptoms to look out for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Active or flashing check engine light<\/li>\n\n\n\n<li>Loss of power<\/li>\n\n\n\n<li>Steady popping\/<a href=\"https:\/\/www.carparts.com\/blog\/why-does-a-car-backfire\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"backfire\">backfire<\/a> in the <a href=\"https:\/\/www.carparts.com\/intake-manifold\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"intake manifold\">intake manifold<\/a> or exhaust (extreme wear).<\/li>\n\n\n\n<li>Loud ticking or tapping sounds<\/li>\n\n\n\n<li>Metal debris in the engine oil<\/li>\n\n\n\n<li>Cylinder misfire<\/li>\n\n\n\n<li>Increased emissions as a result of misfiring<\/li>\n\n\n\n<li>Visible signs of damage<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Active Check Engine Light<\/h3>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/blog\/check-engine-light-flashing\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"check engine light\">check engine light<\/a> comes on whenever your vehicle&rsquo;s computer detects a potential problem that may lead to an increase in emissions.

Your vehicle may hesitate and lose power, jerk or shake aggressively, consume more fuel than usual, and produce more emissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Increased Emissions as a Result of Misfiring<\/h3>\n\n\n\n<p>A worn camshaft can lead to an engine misfire, which in turn, causes an increase in tailpipe emissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Visible Signs of Corrosion\/Damage<\/h3>\n\n\n\n<p>If your car has an OHC (overhead camshaft engine), lifting the cam cover will show you if your camshaft has any visible signs of damage. Look for issues such as worn lobes or scored journals that could indicate an internal failure that has damaged the camshaft.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Camshaft?<\/h2>\n\n\n\n<p><strong>A camshaft is a cast iron or hardened steel <\/strong><strong>shaft specifically timed to half the rotation speed of the crankshaft, which drives the camshaft via a chain, a belt, or directly meshed gears<\/strong>.<\/p>\n\n\n\n<p>The camshaft is typically ground from a single piece of cast steel so that along its length, it has carefully indexed egg-shaped lobes, with one lobe for each valve. There are lobes for the intake valves and for the exhaust valves. The camshaft opens each valve against spring pressure by way of rocker arms or cam followers depending on engine design.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-1024x683.jpg\" alt=\"Close up look of camshaft in white background\" class=\"wp-image-38366\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-1536x1024.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-scaled.jpg 2048w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/04\/Close-up-look-of-camshaft-in-white-background-150x100.jpg 150w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">When a camshaft breaks, the components around it are also at risk of damage.<\/figcaption><\/figure>\n\n\n\n<p>The two primary factors used when grinding the lobes (other than indexing) are <strong>lift<\/strong> (how much the valve is opened) and <strong>duration<\/strong> (how long the valve remains open and how fast it opens and closes).<\/p>\n\n\n\n<p>The camshaft rotates, operating the valves in time with piston travel, which makes the engine a &ldquo;breathing&rdquo; machine of sorts. The firing of the spark plugs triggers combustion, that heats the inert nitrogen, which is mostly what&rsquo;s in atmosphere and in the cylinder. The expanding nitrogen drives the piston, which provides turning force by way of the crankshaft through the flywheel to the transmission. This engine &ldquo;breathing&rdquo; and combustion process only works because of valve timing, which totally depends on camshaft rotation. Depending on your vehicle&rsquo;s engine type, you may have one, two, or four camshafts.<\/p>\n\n\n\n    <div class=\"ai-summary-widget\">\n\n        <div class=\"ai-summary-grid\">\n\n            <div>\n                <div class=\"ai-avatar\">\n                    <figure>\n                        <img decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/q_auto,dpr_auto,f_auto\/carparts\/blog\/widgets\/ai-summary\/ai-bot\" alt=\"AI robot\">\n                    <\/figure>\n                    <span>ELI5<\/span>\n                <\/div>\n            <\/div>\n            <div>\n                <p>A camshaft is a long piece of metal that helps the engine work, kind of like breathing. It has special bumps, called lobes, that open and close little doors called valves. These valves let air and gas in and out of the engine. The camshaft turns at a different speed than another part called the crankshaft. When the camshaft spins, it makes sure the valves open and close at the right times. If the camshaft breaks, it can hurt the engine. Some cars have one, two, or even four camshafts to help them run better.<\/p>    \n            <\/div>\n\n        <\/div>\n\n        <div class=\"ai-summary-tooltip\">   \n            <p>Not everyone is an auto repair expert. <strong>ELI5 (&ldquo;Explain Like I&rsquo;m Five&rdquo;)<\/strong> provides layperson-friendly explanations of complex automotive concepts, systems, &amp; parts, so you can fully understand their importance.

Powered by AI.<\/p>\n        <\/div>\n\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What Happens When a Camshaft Breaks?<\/h2>\n\n\n\n<p>When a camshaft breaks, the components around it are also at risk of damage. The parts most vulnerable to damage are those located inside of your vehicle&rsquo;s engine. These include the other valvetrain components, the crankshaft, cylinder block, cylinder head, pistons, and connecting rods.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<p>A damaged camshaft can snap in two because of a crack or fracture caused by rough handling during shipping or some time before installation. If the camshaft is defective, it may appear bent. The cam can also chip or break off entirely after being hit by any of the engine&rsquo;s rotating parts that may have come loose.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix a Bad Camshaft<\/h2>\n\n\n\n<p>If you&rsquo;re not a professional, it would be best to leave camshaft repairs to a mechanic. This is due to the extent of diagnosis needed before deciding on the best way to fix this problem. What you might have thought to be a completely damaged camshaft may be something else entirely.<\/p>\n\n\n\n<p>Depending on the extent of wear, there are two options for fixing your damaged camshaft:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Replace your camshaft with a new one<\/li>\n\n\n\n<li>Have your old camshaft machined<\/li>\n<\/ul>\n\n\n\n<p>In terms of costs, buying a new camshaft is the most expensive option. A <a href=\"https:\/\/www.carparts.com\/blog\/what-does-remanufactured-mean-vs-refurbished-rebuilt-reconditioned\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"remanufactured\">remanufactured<\/a> camshaft costs less, while machining your camshaft (if it&rsquo;s still usable) should be even cheaper since you&rsquo;re supplying your camshaft to use as the core.<\/p>\n\n\n\n<p>A camshaft replacement can go for anywhere between $50 and $300 plus labor costs. The price varies depending on the camshaft&rsquo;s brand and condition. Depending on the severity of the damage, other related repairs may also be needed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Taking Care of Your Camshaft<\/h2>\n\n\n\n<p>Knowing how to fix a bad camshaft is good, but it&rsquo;s equally as important to know how to keep a camshaft in good condition. This doesn&rsquo;t just mean practicing defensive driving &ndash; it&rsquo;s a good idea to take extra steps to boost your engine&rsquo;s performance, longevity, and reliability.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Regular maintenance; at least twice a year<\/li>\n\n\n\n<li>Keep the engine as clean as possible<\/li>\n\n\n\n<li>Change engine oil promptly to ensure proper lubrication<\/li>\n\n\n\n<li>Check on engine components<\/li>\n\n\n\n<li>Refrain from over-revving the engine<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get a New Camshaft for Your Vehicle<\/h2>\n\n\n\n<p>First things first: if you have a bad camshaft, it&rsquo;s best to stop driving your vehicle. Engine issues are some of the most expensive to fix, so you want to avoid any further costly damage. Thankfully, getting a replacement camshaft that fits your car is easy with CarParts.com.<\/p>\n\n\n\n<p>You don&rsquo;t even have to leave your home to get a new camshaft.
