When blue smoke appears from the exhaust pipe of a car, this indicates that engine oil has entered the combustion chambers. One of the common reasons is the wear of the valve stem seals. With such a malfunction, oil consumption increases, parts of the piston group and the exhaust tract become covered with soot and soot. The car no longer meets environmental standards, so repairs cannot be postponed. Before choosing valve stem seals, you should understand their purpose and determine the main requirements for these small parts. Expert advice will help us cope with this difficult task.
Criterias of choice
Purpose and principle of operation. In an internal combustion engine, all rubbing parts during operation receive a portion of engine oil. Lubrication is required for valve stems and guide bushings. There is a gap between these parts through which oil can enter the combustion chamber. To prevent this, valve seals or valve stem seals are used. Reinforced rubber, flexible fluoroplastic and fluorine rubber are used as materials for the manufacture of parts. The glands are pressed against the valve stem with annular springs.
Requirements for valve stem seals. Several factors have a negative impact on valve seals. It is to them that the parts should have increased durability.
- Inside the engine, the temperature during the combustion of the fuel mixture reaches 1800 ° C. Therefore, the first requirement for seals is high temperature resistance.
- High-quality removal of the oil film from the valve stem is only possible with a snug fit of the cap. Therefore, the second important factor in a quality part is the elasticity of the material.
- Since the stuffing box has to work in harsh conditions of constant friction, wear resistance will become another important requirement. On average, good valve stem seals can withstand about 100,000 kilometers.
- How many valve stem seals you need to buy depends on the type of malfunction. If normal wear and tear occurs due to high mileage, then the entire set changes. But it often happens that one oil seal has failed (a crack appeared, a spring burst). In this case, you should choose a cap of the same size and material.
