Valve cover gasket MITSUBISHI MD303148

Description:

Valve cover gasket MD303148 MITSUBISHI 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.
