Engine Air Valve Pressure Pipe Leak Testing Tool with Ball Valve M12 M14 Thread to 1/4 NPT - Universal for Mustang Ford GM Trucks LS Engine

Engine Air Valve Holder Kit by Guteauto is designed to maintain cylinder pressure to keep the valve closed with compressed air, allowing for easy replacement of the valve oil seal without disassembly. If there is inadequate engine airtightness, you may hear continuous air leakage during the compression stroke, indicating a potential leak that you can locate by listening for damaged parts.

This kit includes a pressure pipe with a 1/4 NPT ball valve and M14+M18 thread, which must be installed at the spark plug position. It is compatible with gasoline-powered vehicles such as cars, trucks, motorcycles, ATVs, and more, but not suitable for diesel engines.
