INSPECTION
COMPESSION PRESSURE
" If the there is lack of power, excessive oil consumption or poor fuel economy, measure the
compression pressure.
"Whenever removing injectors for compression pressure inspection, replace the gaskets with new ones
and tighten them with the specified torque.
1. Warm up engine until the normal operating temperature.
2. Remove the injectors. (Refer to FL Gr.)
3. Check the cylinder compression pressure.
(1) Insert a compression gauge SST(09351-27000, 09351-2A000) into the injector hole.
(2) Fully open the throttle.
(3) While cranking the engine, measure the compression pressure.
Always use a fully charged battery to obtain engine speed of 250rpm or more.
(4) Repeat step 1) though 3) for each cylinder.

This measurement must be done in as short a time as possible.
Compression pressure :
2,157.45kPa (22.0kg/cm², 312.91psi) (200 rpm)
Minimum pressure :
1,863.25kPa (19kg/cm², 270.24psi)
Difference between each cylinder :
98.07kPa (1.0kg/cm², 14.22psi) or less
(5) If the cylinder compression in 1 or more cylinders is low, pour a small amount of engine oil into the
cylinder through the spark plug hole and repeat step 1) through 3) for cylinders with low compression.
A. If adding oil helps the compression, it is likely that the piston rings and/or cylinder bore are worn or
damaged.
B. If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage past
the gasket.
4. Reinstall the injectors. (Refer to FL Gr.)
