The oil slimming cap (in a different valve gland) is a very small, but important engine element. Its main purpose is to prevent leakage of excess engine oil. It must necessarily fit tightly to the valve and skip the amount of oil to be for lubrication. Occarry caps are one of the vulnerable and hard-to-reach parts of the gas distribution mechanism.

The gland is a cap with a reinforced sleeve and spring expendillary, which sealing edge presses to the rod. Effective operation cap is determined by the material of the manufacture. High seal has acrylic fluorine rubber products. It is extremely important to know which caps are installed in the car engine, as when they are replaced, only the original caps need to be used.

The number of engineering caps in the engine is easy to determine: how many valves are so many caps. Different models of the car have a different number of valves.

The oil surcharges are located right on the valves themselves. In turn, the valve is located in the head of the engine block. These products are rapidly wearing and are subject to periodic replacement.

Masters of auto services recommend changing caps every 50,000 kilometers to avoid problems with the engine. The problems can be checked to the touch - change if the gland is solid. Obvious signs of wear: an increase in oil consumption, a naizy, bluish shade of exhaust gases, oil divorces appear on the thread of candles.

Change the oil lifting caps can be independently or on the service. To remove them, you need a special tool - the valve permafector. This procedure is not complicated, but requires certain skills and experience.
To temporarily increase the service life of worn valves, you can use sealing additives. They fill the gaps and soften the valve gland.

Not all the glands have a spring in the working edge. All the glands are different, the normal working gland must be moderately rigid and elastic, there are specimens from both a cold, which can be crushed with two fingers, such a thing can not be put, obviously worried too badly. It is difficult to describe what they should be on hardness, approximately the same as simple glands.
The best will always be those that are accurately accurately, and on the inner and outer side there will be marked, clear, not lubricated and without defects. Noorem without labeling is better not to buy at all, even with good appearance.
