Cylinder leakage testers for Petrol and Diesel engines

  • Each individual cylinder or combustion chamber in petrol (gasoline) and diesel engines can be diagnosed by measuring the engine pressure loss. 
  • The magnitude of the loss of pressure and the location can be determined through the controlled feeding of compressed air into the combustion chamber. 
  • Escaping air or blowing noises in the intake or exhaust area
  • Possible defects: leaking inlet or outlet valves. Escaping air at the crankcase ventilation, oil filler neck or oil dipstick tube
  • Possible defects: wear of piston, piston rings, cylinder track or defective cylinder head gasket.
  • Air bubbles in the cooling water expansion tank or in the combustion chamber of the adjacent cylinder
  • Possible defects: leaking cylinder head gasket, cracks in the cylinder head.
