FAQs
What does a low compression reading indicate?
Low compression readings may indicate worn piston rings, damaged valves, or a blown head gasket.
Can this kit be used on diesel engines?
No, this kit is specifically designed for petrol engines.
How often should I test the compression?
Test compression if you suspect engine problems like misfires, poor fuel economy, or difficult starting.
What is the purpose of the color-coded scales?
The color-coded scales help you quickly assess if the compression is within normal, low, or critical ranges.
How do I interpret the compression readings?
Compare the readings of each cylinder. Significant differences between cylinders indicate a problem. Consult a repair manual for specific engine compression specifications.
How should I store the compression tester kit?
Store the kit in a clean, dry place to protect the components from damage and corrosion.
What should I do if the gauge needle doesn't move?
If the gauge doesn't move, recheck all connections and ensure the engine is cranking properly. Also, consider the possibility of internal engine damage.
Troubleshooting
Gauge reads zero or very low.
Ensure the adaptor is securely screwed into the spark plug hole. Check for leaks in the hose or around the adaptor.
Inconsistent readings between cylinders.
Re-test each cylinder. Ensure the engine is at the correct operating temperature and that the throttle is fully open during the test.
