There is a sharp knock from the connecting rod bearings on the radical move of the “engine” of the car due to the opening of the throttle. To determine the place of such a knock, the spark plugs of the vehicle are turned off alternately.

To eliminate such malfunctions is required:

– Clean the reduction valve from burrs, extra particles; If necessary, then replace the spring (valve);

– carry out repair work of the oil pump;

– make a roller crankshaft to the format to the repair size, change the inserts;
