Engine Lubrication System
Oil is drawn from the oil pan and pressurized by the oil pump. The output from the oil pump is then filtered and distributed through the internal passage ways. Oil is cooled before entering the filter.
All moving parts are lubricated by pressure or splash oil. Pressurized oil is also provided for operation of the hydraulic adjusters, turbochargers and timing gear chain tensioners.
Scheme 503
The engine is lubricated by a forced-feed circulation system with full flow oil filter. The oil cooler forms a unit with the oil filter and fuel cooler which is mounted centrally in the cylinder block between the two banks of cylinders. The engine oil is cooled using the engine cooling system. This eliminates the need for an additional engine oil cooler remotely mounted.
