IMPORTANT: Your warranty is only valid if the turbocharger is fitted in line with these instructions. Turboworks reserves the right to reject a warranty claim if turbocharger is starved of oil or lubricated with contaminated oil at any time. Please retain receipts for all fitting components as well as your warranty card.


  1. Ensure that any fault that caused the previous turbocharger to fail has been rectified.
  2. Check that the engine exhaust, intake and intercooler systems are clean, free from damage and free from oil, gasket pieces, dust/dirt/carbon or foreign objects (including parts of the failed unit!). Any damaged parts must be replaced.
  3. To prevent contamination of the replacement turbo, the oil feed pipe MUST be replaced, irrespective of condition.
  4. Replace engine oil, oil filters and air filters using replacement parts specified by manufacturer.
  5. Inspect the turbocharger oil drain pipe for kinks or carbon blockage. If in doubt, replace the pipe.
  6. Remove all crankcase breather hoses and filters. Clean or renew the filters and hoses in line with the vehicle manufacturer’s recommendations.
  7. Immobilise the engine. Using a clean container to catch the oil, crank the engine over until at least 1/2 pint (300ml) of oil is pumped out of the turbo oil feed pipe. This ensures any dirt or carbon particles, which otherwise may damage the turbocharger’s bearings, are flushed out.
  8. Replace oil pump (Peugeot/Citroen/Mazda/Volvo1.6 Diesel).


  1. Ensure cleanliness while fitting a turbocharger. Do NOT remove the oil feed blanking plug until ready. Do not use exhaust sealing paste.
  2. Connect the oil feed pipe (after completing item 6 above). Do not allow dirt to enter the turbocharger bearing housing.
  3. Before fitting the oil drain pipe, ensure that the blanking plug is removed (where fitted) and crank the engine until oil flows out of the turbocharger bearing housing.
  4. Refit the oil drain pipe.
  5. Check that all connections are tight, but do not over-tighten.
  6. Start engine and check for leaks.
  7. Using a boost gauge, check that the boost pressure is within the manufacturer’s specified limits.
