How to disassemble and assemble the black pipe on Buick Angkewei valve cover

You can go to the repair shop to change it. The black pipe on the valve cover of Buick Angkewei is an exhaust pipe, which needs to be disassembled in a professional repair shop. Exhaust gas enters the throttle valve through the exhaust pipe for secondary combustion. If the exhaust pipe is blocked, the engine pressure will increase, which will easily lead to oil combustion. The symptoms of valve damage are: 1, which will affect the working efficiency of the engine and reduce the power of the car; 2. The engine will have abnormal sound, unstable idle speed or uneven acceleration, and the overtaking performance will decrease. In severe cases, it will also lead to engine starting difficulties, fire, air leakage or increased carbon deposition in the car; 3. The damage of the valve will lead to the unstable operation of the cylinder. Unstable cylinder will lead to engine jitter, poor engine work and blocked exhaust pipe. In severe cases, it will also lead to black smoke from the tail gas. This is a low octane oil. Second, the oil viscosity is low. Go to the 4s shop or repair shop for disassembly and replacement.
