How to check valve stem seals
Valve stem seals, which are a part of the valve system, aid in lubricating the valve to maintain the ideal ratio of fuel to air. An automobile’s power comes from this mixture when it is further burned. Despite their small size, these tiny valve stem seals are essential for maintaining the engine’s proper functioning. In the same way that the valve stems seals certify that the proper amount of lubrication is required, neither more nor less is needed. Faulty valve stem seals cause an entire engine malfunction.
Below you can see how to check valve stem seals:
1. Exhaust Smoke
Don’t confuse this with the white vapor typically seen on engine startup. The most common symptom is excessive exhaust smoke. However, if the white smoke persists after you start the car, it can signify that your valve stem seals have worn out. The oil that has entered the combustion chamber is burning, which is why the smoke is typically blueish-gray. When you accelerate while your car is still in traffic, oil accumulated around the valve seal will be drawn into the combustion chamber, producing a cloud of blue or grey smoke. The valve guide must be strong and precisely crafted since it holds the intake or exhaust valve stem.
2. Conducting a cold engine test
A cold engine test is one of the finest techniques to determine if your valve seal is broken. The seal is now cool after a period of inactivity for your machine, even overnight. The seal will tighten once you turn on the engine. Damaged seals will leave a tiny gap. After that, any leftover oil will collect at the valve cover’s head’s top. Blue-tinted smoke may also come from the exhaust when you start the engine. If this occurs, it signifies that residual oil is leaking into the combustion chamber through the broken seal. Even if it clears after running the engine for many minutes, the bluish smoke, which is burned oil, indicates that the engine requires a new seal.
3. Engine Idling
Pay attention to your equipment if it ever starts to idle. High vacuum levels can result in oil building up around the valve system heads when the engine is at rest, and the valve is closed. When the engine starts to run, you might once again notice blue-tinted smoke if the seal is broken. The oil is being dragged past the seal and into the valve guide. Be sure to turn off the engine and stop using it until you can fix it.
4. Compromised acceleration power
Testing the engine’s compression may also tell you whether the valve stem seals on the engines you utilize in the oilfield and agricultural sectors are failing. You have a valve seal problem and will need replacements if the machine has a higher compression level. On the other side, a lower level can indicate a problem with a piston ring. There are various types of valve guides, and the materials used for the valves must be compatible with the gases or liquids passing through them.
