Low compression may indicate some of
the following conditions:
- Cylinder walls excessively worn out.
- Piston or segments worn out.
- Segments nailed to its seating.
- Valve seating in bad conditions.
- Rupture or other defects in the cylinder head.
NOTE: When the compression is low, check
the engine for the conditions listed above.

ENGINE OIL TUBES
Initial inspection after five hours of use and after 30
hours.
Check that the engine oil tubes are not damaged
and that they have no leaks. If any damage is
detected, change the tubes with new ones.
Check compression
The correct compression of a cylinder indicates that
the internal conditions are good. The decision to
inspect a cylinder is based on the results that we
obtain when measuring the cylinder compression.
Compression verification should be included in
concessionaire inspections.
DATA Compression:
Standard: 1000 Kpa (10.0 Kgf/cm2)
Compression testing procedure
NOTE:
Before checking the engine compression, check
that the cylinder head screws are tightened with
the specific torque value and that the valves are
correctly adjusted.
Warm up the engine before the test.
Check that the battery is totally charged.
Perform the compression measurement in the
following manner:
- Remove the spark plug.
- Thread the pressure gauge in the cylinder head
spark plug thread. Check that the connection is
correct.
- Maintain the throttle valve in the totally open
position.
- Press the ignition button and make the engine run
for a few seconds.
- Note down the value of the maximum reading that
thepressure gauge measures.
