8. Install the oil supply line eye bolt and washers to the turbocharger.

NOTE:

Do not twist the turbocharger oil feed pipe. Twisting of the feed
pipe will result in the collapse and deformation of the plastic
pipe, restricting oil flow and causing turbocharger damage.
During turbocharger replacement, gently push the oil feed pipe
towards the front of the engine to clear the turbocharger.
Assistance may be required to keep the pipes clear of the
turbocharger during removal or installation.
