PossibleCompression pressure kPa kgfcm psi or more

Minimum pressure: 1,030 kPa (10.5 kgf*cm2 , 149 psi)

Difference between each cylinder: 98 kPa (1.0 kgf*cm2 , 14 psi) or less

5. If the cylinder compression in one or more cylinders is low, pour small amount of engine oil into the cylinder through the spark plug hole and repeat steps (a) through (c) for cylinders with low compression.

• If adding oil helps the compression, chances are that the piston rings and/or cylinder bore are worn or damaged.

• If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage past the gasket.

d. Reinstall spark plugs (See ON-VEHICLE INSPECTION ).
