Some PCV systems consist of an orifice (no PCV valve is used on those). 4.0L Jeep Cherokees have a rubber grommet at the rear of the valve cover with a small orifice that can clog. Some Chevy 5.3L pickups have a PCV orifice built into one valve cover but don&rsquo;t have a PCV valve per se, but these orifices can become clogged. | Image Source: Richard McCuistian<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"884\" height=\"1024\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/pcv-valve-diagram-884x1024.jpg\" alt=\"diagram of a pcv valve\" class=\"wp-image-82103\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/pcv-valve-diagram-884x1024.jpg 884w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/pcv-valve-diagram-259x300.jpg 259w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/pcv-valve-diagram-768x890.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/pcv-valve-diagram-150x174.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/pcv-valve-diagram.jpg 1295w\" sizes=\"(max-width: 884px) 100vw, 884px\"><figcaption class=\"wp-element-caption\">A diagram showing the operation of a standard PCV valve. | Image Source: Richard McCuistian<\/figcaption><\/figure>\n\n\n\n<p>Replacing a faulty PCV valve can cost anywhere between $25 and $30 on parts. You can expect to pay around $50 to $70 for labor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Total PCV System Failure<\/h3>\n\n\n\n<p>The PCV system ventilates the crankcase and helps reduce HC and CO emissions by rerouting the vapors to the engine&rsquo;s induction system and burning inside the cylinders.<\/p>\n\n\n\n<p>All PCV systems have their own valve or orifice, an inlet filter, and connecting hoses. In some cases, PCV systems can also have an oil\/vapor or oil\/water separator.<\/p>\n\n\n\n<p>Aside from the PCV valve, the system&rsquo;s connecting hoses can get clogged with sludge. Once the system gets pressurized, engine oil can seep into the intake tube and enter the throttle body.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Worn Piston Rings<\/h3>\n\n\n\n<p>Piston rings can wear out, mainly due to the wrong engine oil, worn-out cylinders, and wrong fuel injection timing.<\/p>\n\n\n\n<p>Worn-out or broken piston rings won&rsquo;t be able to withstand the pressure created by blowby gases, which can lead to excessive pressure buildup inside the crankcase.<\/p>\n\n\n\n<p>Replacing worn-out or damaged <a href=\"https:\/\/www.carparts.com\/piston-ring-set\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"piston rings\">piston rings<\/a> can cost around $50 to $300, depending on several factors. Including labor costs, the total repair bill can amount to up to $1,000.<\/p>\n\n\n\n<p><strong>Note by Richard McCuistian, ASE-certified Master Automobile Technician:<\/strong> <em>Some oil &ldquo;steam&rdquo; deposits are normal inside the intake manifold and on the back side of the throttle plate, even if the engine is healthy.

Sometimes replacing the vehicle battery will create a stalls-at-idle situation because of throttle body clogging and lost adaptive learning.&nbsp;<\/em><\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>Some oil &ldquo;steam&rdquo; deposits are normal inside the intake manifold and on the back side of the throttle plate, even if the engine is healthy.<\/em><\/p>\n<cite><em>&ndash;&nbsp;<\/em><a href=\"https:\/\/www.carparts.com\/blog\/author\/richardmccuistian\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Richard McCuistian, ASE Certified Master Automobile Technician\">Richard McCuistian, ASE Certified Master Automobile Technician<\/a><\/cite><\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of Oil Buildup In the Throttle Body<\/h2>\n\n\n\n<p>Oil inside the throttle body can lead to a series of drivability issues.

However, remember that this symptom could cover a wide range of issues and not just oil buildup in the throttle body.<\/p>\n\n\n\n<p>If you&rsquo;re not familiar with the process of identifying problems with your engine yet, it&rsquo;s always a good idea to bring your vehicle to a mechanic to have it diagnosed.<\/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<h3 class=\"wp-block-heading\">Engine Misfire<\/h3>\n\n\n\n<p>Lack of air because of obstructed passages in the combustion chamber can lead to <a href=\"https:\/\/www.carparts.com\/blog\/what-is-a-misfire-plus-common-obd-codes-linked-to-a-misfiring-engine\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"misfires\">misfires<\/a>. However, keep in mind that there might be other parts that could create the same problem, such as spark plugs and other ignition components.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Poor Acceleration<\/h3>\n\n\n\n<p>Several sensors in the throttle body monitor the engine&rsquo;s airflow to help the <a href=\"https:\/\/www.carparts.com\/fuel-injector\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel injectors\">fuel injectors<\/a> calculate the right amount of fuel.<\/p>\n\n\n\n<p>If there&rsquo;s oil in the throttle body, acceleration can become challenging because the sensors won&rsquo;t be able to identify the amount of air circulating in the engine.<\/p>\n\n\n\n<p>Oil in the throttle body can make your vehicle unusually faster or slower than normal as you step on the <a href=\"https:\/\/www.carparts.com\/accelerator-pedal\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"accelerator pedal\">accelerator pedal<\/a>.<\/p>\n\n\n\n<p>Aside from restricted airflow, other causes for poor acceleration can include low fuel pressure, contaminated fuel injectors, and damaged sensors, among others.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Excessive Smoke from the Exhaust<\/h3>\n\n\n\n<p>Oil in the throttle body can also infiltrate the combustion chamber, affecting the air-fuel mixture. Once this happens, you might notice white smoke coming out of the exhaust.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Rough or Low Engine Idling<\/h3>\n\n\n\n<p>Rough idling is usually an issue caused by restricted airflow, but it can also indicate the presence of oil inside the throttle body. Once oil builds up in the throttle body, it won&rsquo;t be able to produce the right amount of air for fuel combustion.<\/p>\n\n\n\n<p>However, keep in mind that rough idling can mean other issues, such as worn-out <a href=\"https:\/\/www.carparts.com\/spark-plug\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"spark plugs\">spark plugs<\/a>, a faulty <a href=\"https:\/\/www.carparts.com\/fuel-pump\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel pump\">fuel pump<\/a>, a <a href=\"https:\/\/www.carparts.com\/blog\/here-are-the-top-4-signs-of-a-bad-fuel-filter\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"clogged fuel filter\">clogged fuel filter<\/a>, and a faulty <a href=\"https:\/\/www.carparts.com\/distributor-cap\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"distributor cap\">distributor cap<\/a>, among others.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Takeaways<\/h2>\n\n\n\n<p>Oil buildup inside the throttle body can be caused by several failing parts, which are mostly found in the PCV system. These components usually disrupt the engine&rsquo;s airflow, affecting the air-fuel ratio needed for proper combustion.<\/p>\n\n\n\n<p>Once the throttle body is filled with oil, you&rsquo;ll notice several performance-related issues, running from rough idling and poor acceleration to increased fuel economy and white smoke emissions.<\/p>\n\n\n\n<p>However, remember that the symptoms pointing to oil buildup in the throttle body can also be attributed to other issues found in systems other than the PCV. To get an accurate diagnosis, make sure to have your vehicle checked by a trained mechanic.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Buying Replacement Parts for Oil Buildup In the Throttle Body<\/h2>\n\n\n\n<p>The oil buildup in your vehicle&rsquo;s <a href=\"https:\/\/www.carparts.com\/throttle-body\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"throttle body\">throttle body<\/a> can have many different causes, from worn piston rings to a faulty PCV valve.
