1. Ensure that any fault that caused the previous turbocharger to fail has been rectified.
  2. To prevent contamination of the replacement turbo, the oil feed pipe MUST be replaced, irrespective of condition.
  3. Renew the oil filter and engine oil. (refer to your manufacturer’s specifications)
  4. Inspect the turbocharger oil drain pipe for kinks or carbon blockage. If in doubt, replace the pipe.
  5. Remove all crankcase breather hoses and filters. Clean or renew the filters & hoses in line with the vehicle manufacturer’s recommendations.
  6. Immobilise engine. Using a clean container to catch the oil, crank the engine over until at least ½ pint (300 ml) of oil is pumped out of the turbo oil feed pipe. This ensures any dirt or carbon particles are flushed out, which otherwise may damage the new turbocharger’s bearings.
