Do not hold the waste gate valve actuator rod.
When storing the turbocharger sub-assembly, do not store the assembly with the waste gate valve actuator facing down.
Make sure foreign matter does not enter the intake and exhaust ports and oil passage.
If replacing the turbocharger sub-assembly, check for deposits in the turbo oil inlet pipe sub-assembly. If necessary, replace the turbo oil inlet pipe sub-assembly.
If replacing the turbocharger sub-assembly, put 20 cc (1.2 cu. in.) of fresh oil into the turbocharger oil inlet hole and turn the turbine wheel by hand to spread oil over the bearing.
