Ordinary drivers can not guess, what is it GBC in the car. For them there is also an available description which represents GBC as the cover for cylinder blocks protecting them from external influence. This detail, as well as others, can become useless over time or transfer some malfunctions.
What it is GBC?
Asking a question that such GBC in the car, it is possible to allocate the main thing is the detail of irregular shape made of aluminum or cast iron. Make it by means of pointed casting, and it is available in each released car. Before installation it is subjected to mechanical influence for the purpose of artificial aging to get rid of residual tension from casting.
The head of the block of cylinders in the vehicle has in itself a set of details. Each of them has to be fixed perfectly, the correct operation of the engine depends on it. Heads happen two types: the general and w-shaped. The general are established on all standard single-row engines w-shaped on multirow. Knowing GBC - what is it in the car, at any breakage of the motor and parts, important for it, it will be possible to find quicker the reason and to eliminate it.
Where GBC is?
The alloyed cover which hermetically closes cylinders of internal combustion is directly over them. The GBC device very densely adjoins to the block of cylinders and creates the vacuum atmosphere there. It controls the correct operation of pistons and prevents a flame exit outside. Between blocks of cylinders and a head the laying which has to be always correct is located, at some of its damage the correct work will be broken.
What laying of GBC is better?
Knowing all problems of GBC - what is it in the car and other information, it is necessary to choose laying attentively. Correctly picked up will serve longer and will save from expensive repair. Service life depends not only on durability and quality, but also on the correct installation. Fast burn-out and loud knock of pistons or possible failure in the functioning of the engine will be result even of small discrepancy. Now make two views:
- metal;
- paronitovy.
It is considered that the best laying of GBC metal, it will much longer fray, but it suits not all engines. For example, atmospheric approaches more paronitovy as it perfectly smoothes all roughnesses on surfaces. It will perfectly serve long time, only if it is not planned to tune the car and not to subject it to serious loadings.
Signs of malfunction of GBC
Malfunctions happen at all parts of the car and GBC is not an exception. Breakages can cause unpleasant consequences beginning from increase in fuel consumption, to a full stop of a cursor, with the subsequent capital repairs. Experts note the main signs to which it is necessary to pay surely attention to avoid further troubles.
- Oil leak from under a head of the block of cylinders.
- When checking oil on the probe white foam is visible.
- White exhaust smoke.
- Traces of residues of oil in a broad flank and a radiator.
Laying of a head of the block of cylinders - signs is punched
Violation of integrity of laying considerably influences operation of the engine. It is obliged to adjoin densely and exactly, excepting foreign objects and roughnesses. At installation it is necessary to twist very accurately bolts, otherwise service life can be cut by half. There are certain signs of the punched laying of GBC which indicate what actions need to be made not to do much harm.
- Temperature of the engine increases and adheres above to normal norm.
- Antifreeze mixes up with engine oil.
The unusual knock in GBC also says that laying is strongly damaged. It is worth remembering that such breakages are considered as the most dangerous and financially expensive. Troubles in a running gear are able to afford to continue the movement on the car though it and will be unsafe. Problems with heads do not provide any movements if there is no desire completely to change the engine in the vehicle.
Why punches laying of GBC?
Standard breakdown of laying of GBC occurs not at once, and gradually, thereby slowly breaking operation of the engine. It is possible to notice a problem not always in time and in most cases the person continues to use the vehicle. As soon as punches laying completely, the engine in 80% of cases ceases to function. Even regular diagnostics cannot reveal approach of problems with laying, for check it is necessary to remove heads of the block of cylinders. As the main reasons for a gap are considered:
- wrong installation;
- overheating of the engine;
- high compression.
Punched laying of GBC - a consequence
As it was already told above, consequences of this trouble will be not really pleasant. The difference of GBC from other details in the car is that breakage becomes noticeable when it is already impossible to move on it. Such problems can happen and on the way, especially at distant following when the engine works long time in full capacity.
Consequences of malfunction of GBC of laying have negative impact on the engine. If not to pay attention to engine temperature, then along the line it can just overheat and fail. Untimely replacement of laying or installation of low-quality will very quickly have an effect. Repair such in itself noticeable the road, and is better to make once well, than to return constantly to the same
Signs of the burned-through laying of GBC
The main symptoms of the burned-through laying of GBC meet to oil. At those moments when it begins to proceed, foam, drip, etc., it is necessary to check density between cylinders and GBC at once. If there is an oil, then it is desirable it is necessary to address to service for maintenance for laying replacement. It is necessary to choose only the checked services in which there is all necessary for holding this procedure.
Why laying of GBC burns through?
Overheating of a car is the main reason. If GBC burned through, pay attention to operation of the engine, most likely it regularly overheats. It is worth being afraid of hit of the fused gases, for full confidence it is possible to check blackenings on cylinder heads. Always it is necessary to control oil in the engine and to avoid its leak, especially mixing with cooling liquid.
Than to wash GBC?
Each driver himself chooses, than to wash GBC from a deposit. There are no restrictions in this plan, the detail is made of metal which quietly transfers any chemical influences. Some advise to use diesel fuel or acetone, others take powders or various washing liquids. There is no special difference, except for a smell. In house conditions, it is better to take household cleaners not to do much harm to themselves and the relatives in case of careless use of chemicals.
