Turbocharger Installation Check List                                                                   

 Replace oil supply lines and fittings.  These lines often become plugged with decomposed oil which restricts oil flow and drainage.

Do not used silicone or thread tape

Make sure all openings to turbo are open and not plug or capped off.

Shut off fuel or disable ignition and crank the engine for at least 15 seconds or until oil pressure is raised

Allow engine to fast idle (1,000 RPM) for 3 - 5 minutes to seat turbo seals

Always let engine idle for 3 -5 minutes before shut down, otherwise the turbo will continue to spin without oil lubrication and pressure
When changing oil, be sure to prime oil filter
