Compression Check





The minimum compression in any one cylinder is 2069 kPa (300 psi). There should not be more than 345 kPa (50 psi) difference between a suspect cylinder and the average compression of all 8 cylinders.


Cylinder to cylinder variation may be at the high end of the specification on engines with less than 20,000 km (12,427 miles).
