Gas Cylinder Compression Tester:
Use this kit to check valves and rings, inspect for carbon buildup
and late timing. It includes adapters for a wide number of vehicles
(spark plug types/depths).
Gas Cylinder Compression Tester Specifications:
If a normal cylinder, the pressure should be getting higher after
each compression stroke then up to the maximum. The pressure of
each cylinder in the same engine should be within the standard set
by the manufacturer.
If the pressure remains the same or not getting higher until
several compression strokes, then the valve is probably clogged.
If the pressure in two adjacent cylinders is not more than 20 lbs,
lower than another cylinder, then the gasket in the head is
If the pressure is much higher than the standard set by the
manufacturer then probably carbon residue is existed.
If the pressure is low or a big difference between the cylinders,
get a teaspoon of SAE30 oil into each cylinder then test again.
After this test, if the pressure increased much, the problem is
probably the cylinder was not seated properly or the piston ring
was worn out. If the pressure not changed much, then the valve is
Gas Cylinder Compression Tester Features:
This tester is only suitable for gas cylinder (car or motorcycle).
Do not use it on the disel cylinder of car. Be careful, the high
temperature of pressure during test.
During test, if the reading of air gauge is getting up but getting
down after the engine is stopped, then the stop valve in the gauge
is broken and has to be repaired.
