Why Need this Engine Air Valve Holder Pressure Pipe?
- Insufficient cylinder pressure can cause the car to shake.
- Quickly detect the cause of low cylinder pressure, whether it is valve leakage or piston ring leakage.
- Pressurizes the cylinder to raise the valve to convenient replace valve oil seal without dismantling cylinder head.
- Compressed air to help to keep the valve closed when replacing valve springs or valve stem seals, pressurizing the cylinder.
How to Check of damaged parts by listening to the leak position:
- Exhaust pipe leak/noisy means exhaust valve ablation.
- Throttle leak/noisy means intake valve ablation.
- Oil cap leak/noisy means problem of piston ring.
