The Sealey 2 Gauge Petrol Engine Cylinder Leakage Tester is a professional diagnostic tool designed to identify common engine faults quickly and accurately. This dual-gauge system helps mechanics and vehicle technicians pinpoint issues including worn piston rings, damaged valves, cylinder head cracks and blown head gaskets, making it an essential addition to any automotive workshop. The twin gauge manifold displays both the percentage of cylinder leakage and cylinder pressure readings in psi and bar, providing comprehensive diagnostic information at a glance. This allows technicians to assess engine condition precisely and make informed repair decisions without unnecessary dismantling. Suitable for use with any petrol vehicle fitted with 10mm, 12mm or 14mm spark plugs, the VSE2020 offers broad compatibility across most petrol engines. The tester is supplied in a protective storage case with full instructions, keeping the equipment organised and ready for use. For vehicles with spark plugs fitted into deep recesses, the VS200/A or VS200/B Long Reach Compression Tester Adaptors may be required to ensure proper connection.
