For example, the oil can have a difficult time circulating, and the lack of lubrication can make the engine overheat.<\/p>\n\n\n\n<p>Knowing what raises oil pressure will help you take steps to prevent it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes High Oil Pressure?<\/h2>\n\n\n\n<p>High oil pressure can occur due to malfunctioning parts or issues with the oil itself.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bad Sending Unit<\/h3>\n\n\n\n<p>The sending unit measures the engine&rsquo;s oil pressure level, so if it malfunctions, it could result in inaccurate oil pressure readings. For example, a bad <a href=\"https:\/\/www.carparts.com\/fuel-sending-unit\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"sending unit\">sending unit<\/a> might relay that oil pressure levels are high even though they&rsquo;re at normal levels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Clogged Oil Passages<\/h3>\n\n\n\n<p>Oil circulates throughout the engine to lubricate different components. As it flows, it occasionally accumulates all sorts of gunk and dirt. This will typically starve some components for oil rather than causing high pressure, but it depends on where the clogging is happening.<\/p>\n\n\n\n<p>Over time, these contaminants coalesce and create deposits of sludge, dirt, and carbon that can clog the engine&rsquo;s oil pathways. If the passages are restricted, it becomes difficult for the oil to circulate, which increases its pressure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Malfunctioning Relief Valve<\/h3>\n\n\n\n<p>The engine&rsquo;s <a href=\"https:\/\/www.carparts.com\/fuel-pressure-relief-valve\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"relief valves\">relief valves<\/a> limit the levels of compressed air. It reduces oil pressure when it gets too high by providing places for the fluid to flow when pressure levels rise.<\/p>\n\n\n\n<p>If the relief valve malfunctions or gets damaged, there will be fewer places for the oil to flow, raising the pressure. This is the most common thing that causes high oil pressure, but for this to happen, the oil pump relief valve has to stick closed rather than open.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"427\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2024\/03\/automotive-relief-valve-1024x427.jpg\" alt=\"automotive relief valve diagram\" class=\"wp-image-103713\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2024\/03\/automotive-relief-valve-1024x427.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2024\/03\/automotive-relief-valve-300x125.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2024\/03\/automotive-relief-valve-768x320.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2024\/03\/automotive-relief-valve-150x63.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2024\/03\/automotive-relief-valve.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Relief valve opens in response to oil pressure, regulating the pressure in the oil gallery.

This way, they can tell you exactly what might be wrong with your vehicle and what parts you need to replace to fix the problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get Replacements for Parts Damaged by High Oil Pressure<\/h2>\n\n\n\n<p>If you don&rsquo;t take any steps to lower the oil pressure of your vehicle, there&rsquo;s a risk that certain parts will malfunction. For example, the engine oil filter might blow off without warning. Because of this, it&rsquo;s important to change your oil as soon as possible and replace the oil filter. It&rsquo;s also a good idea to replace any components damaged by high oil pressure.<\/p>\n\n\n\n<p>Fortunately, finding high-quality yet affordable replacement parts is easy with the help of <a href=\"http:\/\/carparts.com\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"CarParts.com\">CarParts.com<\/a>.<\/p>\n\n\n\n<p>It only takes a few minutes to find what you need and check out securely.
