to correct defects requires a partial disassembly of the engine and grinding valves.In the context of a home workshop grinding is carried out with the appropriate diameter pyatnadtsatisantimetrovogo hose end is put on the valve (it will serve as a handle).
Using a hammer grind glass to a powder, and then mix it with machine oil.Apply the mixture on the edge of the valve and start the process of lapping.Make sure that during lapping paste does not hit the valve stem, as it may cause serious harm textolite guide handle.
rubber hose, pull on the handle of the valve rod from the opposite side of the head, and then press the valve to the seat and start to rotate.Each time, turn the valve on the thirty degrees.Occasionally break away from the valve seat and repositioned to the new location (this is necessary in order not to remain the largest circular scratches on the surface of the valve and seat).
If the surface of the valve appeared thick gray track half to two centimeters - this is a sign that the process of lapping over.Upon completion of work, wash well with kerosene valve head and seat lapping.Grinding can be done on the engines of all types.
If the mileage of the vehicle exceeded the fifty thousand kilometers, it is time to restore the operating parameters of the engine.For these purposes remetallianty which, when added to the oil contribute to the restoration of worn surfaces of engine parts.These unique "preparations" for a short time produce a self-healing initial geometrical dimensions of parts, increased compression, reducing fuel consumption, as well as normalize the parameters of the car engine.
Be attentive and careful, breaking glass: fragments can be hurt.
low-quality fuel and cold starts to accelerate engine wear.
