2.
Remove the injectors. (Refer to FLB Gr.)
If the there is lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure.
Warm up and stop engine.
Allow the engine to warm up to normal operating temperature.
Remove the injectors. (Refer to FLB Gr.)
Check the cylinder compression pressure.
Insert a compression gauge into the injector hole.
Fully open the throttle.
While cranking the engine, measure the compression pressure.
Always use a fully charged battery to obtain engine speed of 300rpm or more.
Repeat step 1) though 3) for each cylinder.
This measurement must be done in as short a time as possible.
Compression pressure(Standard) :
2,353kPa (24.0kg/cm², 341psi) (260 rpm)
Minimum pressure :
2,059kPa (21.0kg/cm², 298psi)
Difference between each cylinder :
294.20kPa (3.0kg/cm², 42.67psi) or less
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.
If adding oil helps the compression, it is likely 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.
Reinstall the injectors.
