Valve cover flange BMW 11377502022

Description:

Valve cover gasket 11377502022 BMW is a sealing element of internal combustion piston engines with the upper arrangement of valves of the gas distribution mechanism; elastic gasket for sealing the volume closed by the valve cover.

The gasket of the valve cover ensures tightness of the installation of the cover to the head, sealing to prevent oil leakage, protection of valve mechanism parts and oil from contamination (from dirt, dust, exhaust gases, etc.). Therefore, if leaks appear from under the cover, the gasket should be replaced.

Regardless of the type, all valve cover gaskets have the same device. This is a flat elastic part that repeats the shape of the plane of the lid's contact with the head of the cylinder block, which has holes for fasteners and other parts.

Valve cover gaskets are of the following types:

One-piece - a ring gasket or a gasket of a more complex shape, without gaps, which is simply installed under the cover;

Components - a gasket with gaps and inserts for sealing the entrance of the camshaft or other parts;

Complete - in addition to the main gasket, the kit may include additional ring seals for candle wells and other holes in the cover.

They can also be divided into several types based on the material of manufacture:

Rubber gasket - made from different types of rubber, it is the most elastic, but due to the shortcomings of the manufacturing material, it can significantly change its characteristics when the temperature changes (it softens at high temperatures, becomes less elastic in the cold) and generally has less durability.

Rubber cork gaskets - are made on the basis of rubber, to which granulated cork or other porous fillers have been added. This material provides a high degree of sealing and vibration isolation, but gaskets made of it are very demanding on the quality of installation and assembly of the cover, they often require additional treatment with a liquid sealant and have a limited service life.

Paronite gaskets - made of paronite. Paronite can be asbestos-free and asbestos-free, but today manufacturers are abandoning the use of asbestos in favor of safer materials. Paronite gaskets of cylinder head covers are the most widely used today due to their high reliability, resistance to negative influences and good sealing qualities.

Cardboard spacers are made from special types of thick paper that have undergone processing to acquire resistance to oils, gasoline, water and other negative influences. These gaskets are the cheapest, but they are the least reliable, so today they are used on the simplest engines.

Additional Information:

For replacement, you should choose a gasket designed for this particular make and model of the power unit, since the parts for other motors simply will not fit in terms of size and configuration. However, there are options for choosing the material for making the gasket. For new cars under warranty, it is necessary to use a gasket made of the material specified by the manufacturer, in this case, the replacement of the part should be entrusted only to specialists.

About Brand:

  BMW is a well-known manufacturer. The brand can be found on the roads of almost all countries of the world. The main specialization - cars and sports cars, as well as off-road cars and motorcycles. The history of the company began with a small factory. Today, 5 companies in Germany are involved in the production, and another 20 are scattered around the world. BMW is one of the few companies not using robotics. Vehicles and motorcycles are assembled exclusively by hand. After completion, the technical parameters are diagnosed using computers.  During the crisis of 2009, the company's output fell slightly. The decline was 7.6 compared to the previous period. Today, the company plans to increase production by 25% by 2020. Deliveries to the global market reached 2.4 million units in 2016. In the coming years, according to the strategy chosen, these numbers will grow.   The BMW brand is very popular in the world, so the original car parts of the manufacturer are counterfeited by a variety of companies. The simplest way to detect a counterfeit is to use a lighter to heat up the BMW Group inscription on the package. If that one disappears and the letters are replaced by original, the original is before you. If not, then it's definitely fake.
