![]() You can detect this loss of oil with a basic oil dipstick and keeping a regular log of oil levels. This is because oil is being leaked out or burned excessively and causing oil to decrease at a higher rate than normal. High levels of oil consumption is another indicator that you have a bad valve seal. This causes more of this blueish smoke, due to the burning of oil, to come out the tailpipe. In a faulty valve seal situation, when you begin to accelerate again, this oil can end up getting sucked past the seal an into the valve guide. When your vehicle is stopped for a significant amount of time, high vacuum levels will cause the oil to build up around the valve system while it is closed. IdlingĪnother way to test a bad valve seal is to be aware of what happens while your vehicle is idling. This may indicate that your valve is not securely sealed and that it’s time to get a new one. When you start the engine, the oil ends up getting sucked down through the bad seal into the combustion area, producing a blueish smoke out of the tailpipe. When your vehicle has been sitting overnight or for a longer period of time, the top of the head of the valve cover will have some oil left over from the last time you drove. One sure-fire way to tell if you have a faulty valve seal is to perform a cold engine test. Here are some symptoms of a bad valve seal that may need to be replaced: Performing the Cold Engine Test For example purposes, we'll focus on cars, but this can be translated across a variety of systems and industries. Having a proper valve seal can save you thousands of dollars in repairs at the end of the day, so it's important to check them semi-regularly. Some examples of valve seals include: ball valve seats, globe valve discs, stem packing, stem seals, valve discs, valve packing, valve seals, and valve stem packing. Valves have many uses and are found in virtually every industrial process, including water & sewage processing, mining, power generation, processing of oil, gas & petroleum, food manufacturing, chemical & plastic manufacturing and many other fields. Valves are an important part of regulation in any system, and their seals are designed to be used in different types of engines for controlling oil consumption, and valve lubrication.The design and manufacturing of the seal is the key to ensure seal performance and longevity.
