Turbocharger Oil Drain Tubes

• Oil is supplied to the turbochargers to
lubricate and cool the bearings.
• Each turbocharger has it's own drain. The high pressure
turbocharger uses a removeable tube where as the low
pressure turbocharger utilizes a small extension tube off
of a machined passage in the turbocharger pedestal.
• The high pressure turbocharger drain tube is sealed
via two (2) O-rings, one at each end of the tube.
• The low pressure turbocharger drain extension
tube is sealed via a rubber coated metal tube.

Oil Pan / Bed Plate

• The 6.4L Power Stroke
The lower half is wider than the bottom of the engine to
increase the oil capacity of the system. Due to this wider
Lower Oil Pan
oil pan, an upper oil pan is used to adapt the lower pan to
the bed plate. The upper pan also acts as an oil baffle.
• The upper pan is bolted to the bed plate. The bed
plate replaces the individual main bearing caps,
resulting in a more rigid bearing retaining system.
