CHANGE THE ENGINE OIL, OIL FILTER & AIR FILTER
Use only a type and grade of oil which is specified in the vehicle manufacturer's service manual. Oil additives should not be used unless specifically approved by the vehicle manufacturer. Clean and/or replace air filter.

THOROUGHLY CLEAN TURBO OIL FEED LINES
Remove and clean thoroughly or replace lines if necessary. Many non-metal oil lines can have linings crack from movement on the inside that cannot be seen.

INSPECT INTAKE & EXHAUST SYSTEMS TO AND FROM TURBO
Check for and remove any foreign objects. Be very chorough, even small particles can cause major damage when inducted under high speed turbo operation.

REMOVE & CLEAN TURBO OIL DRAIN TUBE
Ensure oil can properly drain through line; restricted drain lines are a leading contributor to turbo oil leaks. Make sure you have the proper oil drain line size for your application.

PRIOR TO INSTALLING
Pre oil the turbocharger with clean engine oil, fill oil inlet port to overflow before connecting the oil feed line. Use only oil specified by manufacturer's service manual. Crank the engine without firing until a steady stream of engine oil flows out of the drain port, then connect oil drain line.
