What's grinding engine

Grinding indicates the operation to rebuild a motor that, due to problems of lubrication, overheating, excessive wear or need repair to return the original features, with the same torque, power consumption and a new engine.

The grinding process of an engine is an operation of high precision machine tools with the specific goal of eliminating the gaps, warping and wear parts, return to their original forms. (See steps in services).

After the worn parts suffer all the steps of rectification, it is necessary to replace the internal engine components such as bearings, bushings, pistons, rings, seals, etc.. These parts should be quality assured by the automakers, so that the engine actually turn over similar characteristics of a new engine.

The internal engine parts when in operation, are in constant friction, subject to great effort and always work at high temperature.

All these factors contribute to the wear of parts. It is considered a normal process and makes use after a certain mileage of the vehicle, usually greater than 200,000 km, it becomes necessary to overhaul the engine ...

The main symptoms that point to the need to rectify an internal combustion engine (gasoline, ethanol or diesel) of a vehicle are ...

1) High consumption of lubricating oil
2) Too much smoke being expelled by the exhaust
3) Low-power
4) High fuel consumption
5) working engine overheated
6) Strong noises coming from the engine

Other factors may determine the grinding, ahead of time, such as working engine overheated, broken timing belt (on some engines), lack of lubricating oil, or low level, or even the terrible habit of some drivers just completed the oil level, keeping the oil for long periods of use, the craze of "rest" your left foot on the clutch pedal, leaving the engine is still cold, and of course, lack of preventive maintenance.

Refinishing can be complete or partial. It is often said, for example, grinding the bottom, which means restoring the portion of the block, which includes shirts of the cylinders, crankshaft, pistons and connecting rods, or rectify the top of the head, valves, valve guides, seats and replacement of the valve timing (in most current engines the camshaft in the head works, and others in the block).

A qualified and suitable, by a careful examination of the engine operation, the guidance on the best solution for grinding.
