First, there is increased noise, strange knocks, then the consumption of automobile oil increases sharply and blue smoke appears from the muffler. Also, such a car does not start well, and when driving, it suddenly starts to stall.

Engine overhaul is a complex set of works, which includes the restoration of its technical characteristics through complete disassembly and subsequent repair. Almost all engine parts are overhauled: crankshaft, cylinder head, as well as the cylinder block itself and much more.

What factors can cause a car's heart to break down? Even those engines sometimes get to the service station, the mileage of which is not even a hundred thousand. An engine is not a piece of scrap metal and should be handled with care. And those who do not adhere to the necessary rules of operation, later bitterly pay for it. First of all, an unforeseen breakdown can be caused by a formal disregard for regular oil and oil changes.filter. These, at first glance, small details play a very important role in the operation of the engine.

When the filter is worn out, the oil simply does not get into the engine, as a result of which the pistons run dry. After a few minutes of such work, the motor may finally jam. Only a complete engine overhaul can save him. Also, the motor can jam even with a good filter, if low-quality oil is poured into it.

When the engine "no longer breathes", motorists ask themselves the question: "Repair the old one or is it better to buy a new one?" Of course, the new motor will last longer than the newly restored one, and it will take less time to replace it - one day (maximum two). But not everything is as simple as it seems at first glance.

The cost of a new engine is sometimes several times more expensive than the cost of a plumbing repair. Also, when replacing this part with a new one, the driver will have a lot of trouble with documents. After the replacement, you need to register a new engine number with the traffic police, and this is not easy, and very expensive.

Usually, "new" engines are removed from emergency cars that have been involved in an accident. The price for them is much lower than for really new motors. But due to lengthy and expensive registrations at the traffic police, many drivers decide to overhaul the engine.
