The reasons for the oil leakage of automobile engine: First of all, most of the oil leakage of the engine is caused by the aging or damage of the seals. The seal will slowly harden over time and with continuous heat and cold alternation, and may break if it loses elasticity (technically called plasticization). resulting in oil leakage. Aging seals are common from the top, middle and bottom of the engine. One of the more important seals on the top of the engine is the valve cover gasket.

Valve cover gasket: This should be the most common. You can see from the name that it is usually installed on the valve cover. Due to the large sealing area, it is easy to cause oil leakage due to aging over time. Correspondingly, most cars have a long age. owners have encountered. The gasket needs to be replaced. The main hazards of car engine oil leakage: loss of oil, resulting in waste, serious oil shortage may lead to engine damage. It is not caused by the oil leak, but because the oil pressure is insufficient after the leak, so just pay close attention to the oil level.

1. Engine oil leakage caused by poor sealing such as valve cover gasket, oil radiator, oil filter, distributor housing bearing hole, rocker cover, cam bearing rear cover and engine bracket plate deformation situation.

2. When the front and rear oil seals of the crankshaft of the car and the oil pan gasket are damaged to a certain extent to a certain extent, it will also lead to engine oil leakage.

3. If the timing gear cover gasket of the car is not properly operated during installation, or when it is damaged to a certain extent, the screws are loosened and oil leaks.
