For diagnosing compression pressure lossSuitable for analysis of inlet and outlet valves, piston rings or cylinder liner, cylinder head or head gasketBetter alternative for compression measurementsuniversal useIntegrated pressure reducerRequired working pressure: 1.0 barFor use on motors at operating temperaturesIn sturdy plastic caseAnalysis results:Exhaust valves leaking: Air noise in the exhaust, manifold or Cylinder head on the outlet sideInlet valves leaking: Air noise in the inlet tract, on the cylinder head on the inlet sidePiston rings, pistons, cylinder track damaged: Noise from the crankcase vent or the dipstickFaulty cylinder head gasket: Air noise in the adjacent cylinder, spark plug boreFaulty cylinder head gasket or cracks in cylinder head: Air noise or bubble formation in cooling system or expansion tankThis text is machine translated.
