Compression Pressure:

3S-GTE 11.5kg/cm^2 (164psi, 1,128kPa) or more.. with 9.0kg/cm^2 (128psi, 883kPa) as a MINIMUM


5S-FE 12.5kg/cm^2 (178psi, 1,226kPa) or more..with 10.0kg/cm^2 (142psi, 981kPa) as a MINIMUM


Difference between each cylinder:
1.0kg/cm^2 (14psi, 98kPa) or less


If the cylinder compression in one or more cylinders are low, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat check 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.



Torque needed on spark plugs to reinstall them:

180kg/cm (13ft/lb, 18N/m)
