Recommended Procedure
Note: When you install a turbocharger, do not remove the cap for the oil supply and the cap for the oil drain until the oil lines are ready to be connected.
When the turbocharger is installed, install the correct strainer in place of the gasket at the oil inlet.
Connect the turbocharger oil supply line and the turbocharger oil drain line.Note: It is very important to remove the strainer after 30 minutes of operation. The strainer may become plugged. This could result in a lack of lubrication for the turbocharger bearings. This could result in a failure of the turbocharger.
Operate the engine for 30 minutes at full load. Shut down the engine.
Disconnect the turbocharger oil supply line in order to remove the strainer.
Install a new gasket in place of the strainer.The 1S-6595 Gasket has two bolt holes that are spaced 38.1 mm (1.50 inch) from each other.The 4P-4460 Gasket has two bolt holes that are spaced 44.5 mm (1.75 inch) from each other.
Reconnect the oil supply line to the turbocharger.
