Tuyue throttle exhaust valve cover is broken.

Go to the car 4s shop for repair and replacement. The reason for this failure is: 1, engine valve timing is damaged (including, of course, slippage, fracture and deformation of timing belt or chain teeth (tooth filling teeth)). 2. The linkage mechanism is loose. 3. Because the oil pressure is too high, the dry friction of the valve mechanism is stuck in the open position. 4. The valve snap ring (pin) is damaged, broken and falls off. In severe cases, it will occur: piston rupture, connecting rod bending, cylinder tube rupture and cylinder head scrapping. Caused by aging. The valve of the car is broken. Changing the cylinder head depends on the specific situation. Soap can be dripped on the valve of a car. If it bubbles, the valve is broken. If it doesn't bubble, the valve is not broken. The rupture of the valve will cause the corresponding cylinder not to work. When a cylinder does not work, the engine will tremble and the engine will not work.
