Turbocharger Overhaul: Inspection

  1. Inspect turbine housing and blades for cracks or damage. Ensure turbine rotates freely and turbine blades do not contact housing. Ensure wastegate valve operates freely. Ensure oil passage in cartridge assembly is clear.
  2. Leak test wastegate valve actuator diaphragm with a hand-held vacuum pump. If wastegate actuator operation is tested by applying pressure to diaphragm, DO NOT  apply more than 12.4 psi to diaphragm.
CAUTION: Oil leakage could result if new "O" ring is damaged when installing into groove on cartridge assembly.
