Turbocharger Feed Line; Crankcase Oil And Coolant Passages - International VT 275 V6 Manual

Turbocharger Feed Line

• Pressurized oil from the filtered passage in
the oil-filter adapter is supplied to each
center section of the twin turbocharger.
The oil is transferred through a hose to
the turbocharger.
• The turbocharger ends of the hose are
sealed with face seals. The oil filter adapter
end of the hose pushes into a cavity on the
filter adapter and is sealed with O-rings
and retained by a single cap screw.
