Engine oil leakage emergency treatment
High pressure tubing leaks. This is often due to the fact that the ball joints at both ends of the high-pressure fuel line have loose contact with the tight seat of the oil outlet and the concave surface on the injector. Therefore, when installing a high-pressure fuel pipe, be sure to pay attention to the tight fit of the various components, the middle can not be mixed with dirt. In the event of serious wear of the ball joint and the concave surface during use, a small piece of copper mat can be cut from the waste cylinder and tightened with a nut. Valve cover leaks. Valve cover is made of thin steel plate or aluminum products. During installation, if the screws are too tight, it is easy to deform and leak oil. At this time, it can be unloaded and tapped gently with a wooden block to restore it to a smooth level before reinstalling it. The middle gasket is preferably lacquered on the cylinder pad to prevent damage when disassembled. Injector return oil. If the nozzle is used for a long time, the needle valve and the guide hole are exposed to increased wear gaps, and it is easy to return oil. When this phenomenon occurs, on the one hand, the return pipe must be densely connected to allow the oil to flow back to the tank or to the filter; on the other hand, the pressure of the fuel injection can be increased to prevent oil leakage.
