The following installation instructions are applicable to most makes of turbo.
to follow these instructions (which are also supplied in print
with each turbo supplied) can lead to turbocharger damage and
may void warranty.
the calibration of a wastegated turbo may damage
the turbo/engine and voids warranty.
gaskets must be used - they must not overlap holes.
Gasket covering part of oil hole - reduces oil supply to
if gasket material breaks away, may totally stop oil
flow. Gasket clear of oil hole. Liquid gasket or sealants
recommended, particularly for the oil inlet/outlet.
Excess material may break away, reducing or stopping oil
to engine/vehicle manufacturers literature for correct oil
type and quantity. Also, for torques and installation details.
Prevent dirt/debris from entering any part of the turbo during installation.
Installing The Turbo
air hoses connected to the turbo must be totally clean and
filter and housing must be totally clean and free from debris.
engine breather system and check function.
old gasket material from the exhaust manifold and pipe. Faces
must be undamaged.
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.
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.
feed and drain lines must be totally clean and undamaged
- oil flow must be unrestricted. Check that
oil feed line is not too close to source of heat. Oil
level OK, but drain line damaged - causes oil leaks from
oil drain line. Refill the oil inlet hole with new clean engine
oil and reconnect the oil feed line.
air hoses and tighten.
new air, oil and fuel filters, refill engine with new engine
possible, prevent the engine from firing and crank the engine
for 10-15 seconds to prime oil feed. Start the engine and idle
for 3 to 4 minutes before increasing speed. Check for oil and
engine and re-check engine oil level. Note: oil level should not be above the point where oil returns from
the turbo to the engine.
level too high - blocks oil drain from turbo - causes
oil leaks from turbo.
level correct to specification.
crankcase pressure. High pressure may be caused by piston bypass
or blocked breather system.
High crankcase pressure can stop oil from draining - causes
oil leaks from turbo.
please adhere to any 'special' fitting conditions ie replace
with manufactures modified parts, attached to your turbo unit.
