1986 TOYOTA SUPRA oil level

PRECAUTION
1. Do not stop the engine immediately after pulling a trailer
or after high speed or uphill driving. Idle the engine for
20±120 seconds, depending on how hard the vehicle has
been driven.
2. Avoid sudden acceleration or racing immediately after
starting a cold engine.
3. Do not run the engine with air cleaner removed, as this
may cause foreign material to enter and damage the
impeller wheel operating at high speed.
4. If a turbocharger is found to be defective and must be
replaced, check for the cause, and repair or replace the
following items as necessary:
wEngine oil level and quality
wConditions under which the turbocharger was used
wOil lines leading to the turbocharger
5. Use caution when removing and reinstalling the
turbocharger assembly. Do not drop it or knock it against
anything or grasp it by easily±deformed parts, such as
the actuator or rod, when moving it.
6. Use caution when removing and reinstalling the exhaust
gas control valve assembly. Do not drop it or knock it
against anything or grasp it by easily±deformed parts,
such as the actuator or rod, when moving it. The control
valve is ceramic.
7. Before removing the turbocharger, plug the intake and
exhaust ports and oil inlet to prevent entry of dirt or other
foreign material.
8. If replacing the turbocharger, check for accumulation of
sludge particles in the oil pipes, and if necessary,
replace the oil pipes.
9. Completely remove the gasket adhered to the lubrication
oil pipe flange and turbocharger oil flange.
10. Whe n re pla c ing bolt or nuts , us e only authorize d
replacement parts to prevent breakage or deformation.
11. If replacing the turbocharger, pour approx. 20 cm
3 (1.2 cu
in.) of fresh oil into the turbocharger oil inlet and turn the
impeller wheel by hand to spread oil to the bearing.
12. If overhauling or replacing the engine, cut the fuel supply
after reassembly and crank the engine for 30 seconds to
distribute oil throughout the engine. Then allow the
engine to idle for 60 seconds.
