In many parts of the car has a small orifice, holes are closed, will lead to failure. So what holes are not blocked it?

    Once the excess pore water pump hole of the pump blocked die, the water will leak into the pump bearing lubrication to destroy the environment, resulting in premature wear of bearings and shaft.

    Pump pump pump drain hole on a number of vent hole, if the leak hole blocked, leaking diesel fuel pump will not discharge pump, and piston from the pump into the fuel pump at the bottom shell, so that oil dilution, deterioration, so that poor lubrication inside the pump.

    Vent charging the battery, the battery electrolyte within the reaction will produce a lot of gas, the gas discharged from the vent, if the vent is blocked, the gas will accumulate too much, the pressure will rise within the battery , will result in battery explosion serious accidents.

    Injector diesel injector holes are spill return pipe, so that no excess sprayed into the cylinder to return the fuel tank of diesel. Some owners believe that if the return pipe plug, can increase the amount of oil into the cylinder, so the engine more "strong and." In addition, some owners due to the return pipe is damaged, too late to repair, to prevent diesel spills, people blocked oil hole, is wrong.

    Some of the engine fuel pump fuel pump on a respirator with breathing apparatus, its role is to ensure that Injector work indoor heat oil and gas that comes out in time to prevent the intrusion of external dirty air and impurities. Damage fuel pump respirator, some owners do not repair it directly at the hole the plug, which will lead to deterioration of lubricating effect.
