Compression check in engine cylinders
To check whether a tightly fitting valves, if not worn piston rings, there is no any other fault in the cylinder, measure the engine compression. The engine must be at operating temperature.
On the VR6 engine control the engine compression is associated with some difficulties, because it requires using a special tool to remove the plugs spark plugs and spark plugs themselves.
If there is a fear that a bad cylinder compression, the most reasonable to address the service station. In addition, if the vehicle has an engine VR6, you can choose between STO ?«Ford?» and ?«Volkswagen?».
The magnitude of compression to the following conclusions:
- Normal contraction of 1.0-1.3 MPa
- The border wear 750 kPa.
