![]() ![]() ![]() Make sure to shut the engine down and remove it from operation until you can get it repaired.ĭepending on the engines you use in the oilfield and agricultural industries, testing the engine’s compression can also help determine if your valve stem seals are deteriorating. That means the oil is getting pulled past the seal and into the valve guide. If the seal is faulty, you may once again see blue-tinted smoke when the engine begins to run. When the engine is at rest, high vacuum levels can cause the oil to build around the heads of the valve system while the valve is closed. Pay attention to your machines if they ever idle. While oil leaks are often a clear warning of faulty valve seals, they may not always be visible, so don’t rely on this as a guaranteed warning because the oil could be burning off. You can make this part of your regular maintenance schedule. Make sure to check the engine’s oil level with a dipstick, and refer to your oil log to see if the fluid levels differ. Unburned fuel in the exhaust skyrockets the converter’s operating temperatures, which can cause the converter to overheat and create a blocked exhaust. Burning oil increases emissions and can contaminate the catalyst. When oil leaks or burns at higher rates, the seal no longer controls the oil flow. If you notice you’re going through more oil than usual, it can be another indication of a bad seal. Be aware of specific machine movements that cause more smoke than usual. The excessive smoke may also come in more consistent waves as the engine runs for long periods. ![]() However, when you start seeing it last longer than usual or appear a different color, you know a faulty seal may be the cause. The bluish smoke, which is burned oil, signifies that the engine needs a new seal, even if it clears after several minutes of running the engine.ĭepending on the machines and equipment you use, smoke is often a common form of exhaust. If this happens, it means the residual oil is passing down through the damaged seal and into the combustion chamber. When you start the engine, you may also see blue-tinted smoke appear from the exhaust. Leftover oil will then settle at the top of the valve cover head. Once you start the engine, the seal will contract. After your machine hasn’t run for a while - even overnight - the seal is now cool. One of the best ways to tell if you have a faulty valve seal is to conduct a cold engine test. Six ways to assess whether you have a faulty seal on your hands include: A damaged seal can cause engine oil flooding that will lead to engine failure. However, excess oil can result in carbon buildup, which can lead to many issues, such as:Įssentially, valve stem seals prevent oil from entering the combustion chamber from the cylinder head. ![]() Otherwise, too little oil can cause various components to wear as parts rub together. A controlled amount of oil is crucial in maintaining adequate lubrication. Valve stem seals control oil consumption and lubricant in an engine by allowing a specific amount of oil inside the valve stem as it moves. How to Check If Your Valve Stem Seal Is Faulty.6 Signs Your Valve Stem Seal Is Leaking.Learn how to find faulty seals and what you can do to avoid these issues. Here is where Global Elastomeric Products comes into play. No one wants to face valve issues because they indicate a severe problem within your machine’s engine. But how do you check for bad valve seals, and what signs should you be aware of? Having a valve stem seal that works correctly within any of your applications can save you time and money by eliminating the need for lengthy engine repairs and replacements. Please see each item for details if needed in their category.Valve seals precisely control the amount of oil entering the valve stem system, making them critical components in maintaining your engine’s compression levels.
