Note: if there is insufficient power, increased oil and / or fuel consumption, measure the pressure at the end of the compression stroke.
Check the pressure at the end of the compression stroke in the cylinders.
- A) Warm up the engine.
- b) Remove the coils and remove the spark plugs.
- V) Remove the fuel pump relay.
- G) Insert the compression gauge into the spark plug hole.
EJ series.
KZ series.
d) Fully open the throttle.
e) Turning the crankshaft with a starter, measure the pressure.
Note: Always use a fully charged battery to get 300 RPM or more.
and) Repeat steps with (G) By (e) for each cylinder.
Note: measurements should be taken in as short a time as possible.
Pressure at the end of the compression stroke:
K3-VE:
- nominal — 15.0 kg/cm2
- minimum — 11.0 kg/cm2
K3-VE2:
- nominal - 13.1 kg / cm2
- minimum - 9.1 kg / cm2
EJ-VE:
- nominal - 15.7 kg / cm2
- minimum - 13.9 kg / cm2
Pressure differences between cylinders - no more than 1.5 kg / cm2
h) If the pressure at the end of the compression stroke is low, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat steps from (G) By (e) for low pressure cylinders at the end of the compression stroke.
If the addition of oil increases end-stroke pressure, the piston rings and/or cylinder bore may be worn or damaged.
If the pressure remains low, the valve may be sticking, or there is a loose seat in the valve seat, or there is a leak through the cylinder head gasket.
