Oil pump
The oil pump is situated above the oil pan. The oil is drawn in through the filter in the bottom of the sump and
simultaneously through the engine return duct while driving. All engine lubrication points are swept from the
pressurised oil side.
Oil filter module
The oil filter module is designed as a full-flow filter. For easy maintenance, it is accommodated in the inner
vee of the engine. The filter element can be easily replaced without the need for special tooling. It is made of
a polymer-based nonwoven material.
