What you need to replace the cylinder head gaskets?

Head of cylinder blocks – one of the most important parts of the vehicle, the quality of which directly affects the car's dynamic performance. In the head are the combustion chamber and the valve mechanism, which is an essential part of distribution system.

The cylinder Head bolted to the block, so much so that the bolts or studs that are used for this purpose, are used only once, after which they become unsuitable for this operation as extended.

So, between them installed the head gasket the cylinder block. There are moments that her replacement is simply necessary.

In replacing the gaskets cylinder head – the procedure is not too difficult since, like it or not, precedes the removal of the cylinder head. Of course, there may be some problems, but the head gasket cylinder block – a very important detail, the replacement of which takes place exclusively in extreme cases.

In principle, cases where it may become necessary to replace cylinder-head gaskets, a little bit. First – it is usual repair of the engine, wherein the removable head. The fact that the steel rings that framed the inside edge, with a strong attraction are pressed and become unsuitable for reuse. In addition, the head includes channels for flow of lubricant and coolant. Their edges become ragged. Also on both sides of the strip damage resistant sealant. Its restoration is impossible, but nowadays all the details are available in the nearest shop.

Oil consumption in the engine. Six reasons

It is Hardly possible to find a motorist who would not be worried about the increased oil consumption. It is especially annoying when it happens with another new motor. Here are the most common causes that result in the consumption of oil in the engi...

In addition, replace the cylinder head gaskets is due to the poor quality of Assembly after installing the head, since the latter could be pulled with insufficient force. Then on its surface can be seen traces of leaks of oil or coolant. The penetration of the first substance between the gasket and mating parts leads to inevitable consequences in the form of fluid leaks, flooded into the engine block.

More problematic is the gasket replacement cylinder head in case of burn-out. This is another consequence of the loose fitting. As is known, the temperature in the combustion chamber during the explosion of the combustible mixture reaches 800 degrees. Therefore, the cylinder-head gasket typically made of paronite in steel framing. However, the steel rings are located only on the inner edge, so leakage emissions beyond their limits leads to a drastic lowering of compression in the cylinder, possibly none. As a consequence of the loss of power. Such a problem can be identified by characteristic noise. In addition, such a channel may enter the cooling or lubricating fluid. This leads to their release into the engine compartment.

When the intake stroke in the cylinder a vacuum is created which sucks oil from the oil system through the hole.

In principle, this problem is quite rare but if it occurs, delaying elimination is not necessary, because such a small thing can completely remove the engine failure.
