Engine Lubrication System: Notes
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
Lubrication system is a full-flow filtration, pressure-feed type. Oil, stored in oil pan, is taken in and discharged by a rotor type pump directly coupled to crankshaft. Pressure is regulated by a relief valve. Oil is fed through a filter to the crankshaft journals from an oil gallery in the cylinder block. The same gallery feeds oil under pressure to cylinder heads. Oil flows to each cylinder head, then through passages to camshaft journals, rocker shafts, rocker arms and hydraulic lash adjusters. See Figure.
