IMPORTANT :
turbocompresseur 1. Failure to follow these instructions can lead to turbocharger damage and may void warranty.

2. Changing the calibration of a wastegated turbo may damage the turbo/engine and voids warranty.

3. Correct gasket must be used- they must not overlap holes.
  • The gasket covering partof oil hole reduces oil supply to turbo or if gasket material breaks away, may totally stop oil flow.
  • Gasketclear of oil hole. Liquid gasket or sealants are not recommended, particularly for the oil inlet/outlet. Excess material may break away, reducing or stopping oil flow.
4. Refer to engine/vehicle manufactures literature for correctoil type and quantity.Also,for correct torques and installation details.
5. Prevent dirt/ debris from entering any part of the turbo during the installation process.

6. Before fitting the turbocharger, check that the part number is the correct one for the engine- fitting the incorrect turbo to an engine may damage the turbo/engine and will void the warranty.

INSTALLING THE TURBO :
• All air hoses connected to the turbo must be totally clean and undamaged.
• All filter and housing must be totally clean and free from debris.
• Clean engine breather system and check function.
• Remove old gasket material from the exhaust manifold and pipe. Faces must be undamaged.
• Remove plastic or foam blanking plugs from the turbo before fitting.
• Fill the oil inlet hole of the turbocharger with new engine oil and spin the compressor wheel by hand a few times- it should spin freely.

Note : It is normal to feel some up and down movement on the wheels.
• Fit turbocharger onto manifold or engine block (as applicable) using the correct new gasket or joint ring, then reconnect the exhaust pipe. Tighten all nuts/bolts.
• Oil feed and drain lines must be totally clean and undamaged-oil flow must be unrestricted. Check that any flexible hose liners have not collapsed internally. Check that oil feed line is not too close to source of heat.
• Oil level OK, but drain line damaged- causes oil leaks from turbo.
• Fit oil drain line. Refill the oil inlet hole with new clean engine oil and reconnect the oil feed line.
• Fit air hoses and tighten.
• Use new air, oil and fuel filters, refill engine with new engine oil.
• If possible, prevent the engine from firing and crank the engine for 10-15 seconds to prime oil feed. Start the engine and idle for 3to 4 minutes before increasing speed. Check for oil and gas/ air leaks.
• Stop engine and recheck engine oil level.

Note : Oil level should not be above the point where oil returns from the turbo to engine.
• Oil level too high- blocks oil drain from turbo- causes oil leaks from turbo.
• Oil level correct to specification.
Check crankcase pressure. High pressure may caused by piston bypass or blocked breather system.
• High crankcase pressure can stop oil from draining- causes oil leaks from turbo
