The inspection found insufficient pump oil pressure, decomposition pump, found that the valve gasket was significantly scratched, and there is a fracture.

A starter motor works as follows:

When a current is supplied to the solenoid it engages the plunger.this moves the lever fork and in turn pushes the pinion on the starter motor drive shaft.
the movement also closes high current contacts (brushes) for the starter motor which then begins to turn.together with the rotation and engagement of the pinion to the engines flywheel the starting process is complete.when the ignition switch is released and the current is no longer supplied to the starter motor the solenoid

retracts. this moves the pinion away from the ring gear and the starter motor becomes inoperative.excessive cranking or vehicle faults resulting in the starter motor remaining engaged can result in excessive heat generation and the premature failure of the starter motor and/or its components.
