How to assemble and disassemble Nissan Qi Jun valve cover?
The Qi Jun bonnet can be removed by unscrewing the bonnet bolts with a wrench. The valve cover is mainly connected with the cylinder head of the engine. The camshaft is installed under the valve cover, and some parts of the intake mechanism on the cylinder cover are sealed, so as to ensure the normal operation, lubrication, protection and dustproof sealing of the valve drive mechanism and all parts of the engine, forming a closed whole, thus ensuring a good working environment for the internal parts of the engine. The following are the effects of valve cover failure: 1. Affect the lubrication of the vehicle, the oil leakage of the valve cover will lead to insufficient lubrication of the valve cover, which will cause parts to wear and damage the engine for a long time; 2. The air tightness of the engine will be affected, and the working air pressure of the engine will also leak from the oil leakage. The engine has exhaust gas connected to the throttle through the broken valve, and the air leakage will affect the stability of the engine. 3. It will cause the engine to be dirty and even catch fire. The leaked oil will flow along the engine and combine with dust to form sludge. If you encounter an open flame, it will ignite the engine, which is very dangerous.
