The complete kit includes pressure regulated manifold with dual gauges, 24 in What is a leak down test A leak down test is a method of using compressed air and a specialized gauge set that reads differential pressure to evaluate the condition of an engine's cylinders, pistons and rings, and valves and seats without disassembling the engine. The jegs automotive leak down tester includes an adjustable air regulator, two pressure gauges, an air chuck, and a hose attachment This dual gauge is ideal to check leak down and set barrel valves on fuel injection systems without running the engine Detects ring seat failure, bent valves, cracked heads, and leaking gaskets
Works best with 100+ psi air source Compression leak tester hooks up to air compressor (provide yourself) can help to detect common engine faults such as worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets Leak down tester gauge also equipped with 18 rubber hose, ar2000 pressure regulating valve, american type air plug and aluminum body. It can directly display the pressure value and leakage rate of the tested cylinder cylinder dual gauge leak tester kit versatility. This leak down test kit diagnoses internal engine problems with ease Includes multiple thread adapters for different engines
6) adjust the regulator on the leakdown tester so the the right gauge indicates 0 7) connect the spark plug adaptor hose to the coupler of the leakdown tester 8) read the leak down percentage on the right hand gauge.
