On the VR6 engine, the control of compression in the engine cylinders is associated with some difficulties, since this requires using a special tool to remove the spark plug plugs and the spark plugs themselves.
If there is a fear that one of the cylinders has poor compression, then the most reasonable thing to do would be to contact the service station. In addition, if the car is equipped with a VR6 engine, then you can choose between service stations «Ford» and «Volkswagen».
The following conclusions can be drawn from the compression ratio:
- normal compression 1.0—1.3 MPa
- wear limit 750 kPa.
