Why Need this Engine Air Valve Holder Pressure Pipe?
- The car may tremble if the cylinder pressure is insufficient.
- Find the source of low cylinder pressure as soon as possible, be it valve or piston ring leakage.
- Uses pressure to raise the valve without removing the cylinder head, making it easy to replace the valve oil seal.
- When replacing valve springs or valve stem seals, pressurized air can help maintain the valve closed by pressurizing the cylinder.
