How much do you know about the valve oil seal, one of the crucial components of the engine valve set, that needs to be replaced once every 20,000 to 30,000 kilometers of driving?

A valve oil seal is what?


For the engine valve guide rod seal, a valve oil seal is a type of oil seal that is typically made of an exterior skeleton and fluorine rubber that has been vulcanized together. The oil seal's diameter mouth is installed with a self-tightening spring or steel wire. An effective valve oil seal can stop engine oil from leaking into the combustion chamber, preventing gasoline and air mixture and exhaust gas leaks and keeping oil from entering the intake and exhaust pipes, all of which can result in oil loss. One of the crucial components of the engine valve set, the valve oil seal comes into contact with gasoline and oil at high temperatures, necessitating the use of materials with exceptional heat and oil resistance, most frequently fluorine rubber.

What the valve oil seal does is:


1. To prevent oil loss, avoid letting oil into the intake and exhaust pipes.
2. Stop the leakage of exhaust gases and gasoline mixtures.
3. Ensure that no engine oil enters the combustion chamber.

A damaged valve oil seal has the following effects:


1. When the car is cold-started, it causes the oil to begin burning and produce blue smoke.
2. Vibration and slow acceleration will start to affect the engine.

In reality, valve oil seal failure is uncommon; instead, aged corrosion brought on by burning oil is more typical. In most cases, valve oil seal issues are present after the car starts to emit cold blue smoke. The usual approach is to disassemble the valve oil seal and repair it. However, this method is time-consuming, expensive, and labor-intensive. In addition, because of the parts' quality, assembly methods, and other unreliable influencing factors, sometimes we end up creating more issues.
