The low friction bearings of the turbocharger rely on a steady flow of clean oil. The oil, supplied from the lubrication system of the engine, provides lubrication to the turbocharger bearings.
To maintain the life expectancy of the turbocharger, it is essential that the oil has a free flow through the turbocharger and unrestricted return to the oil pan. It is therefore imperative that the engine oil is replenished at regular service intervals with the recommended quality and quantity of oil.
The oil supply pipe transmits the engine oil from the oil filter housing to the turbocharger. The oil supply pipe is fixed by a Banjo bolt and sealed by two washers on each end.
The oil return pipe transmits the engine oil from the turbocharger back to the oil pan. The lower end of the oil return pipe is pushed into the cylinder block and sealed by an O-ring seal. The upper end of the oil return pipe is retained by a bolt and sealed by an O-ring seal.
