LR3/Disco 3
General
Oil is drawn from the reservoir in the oil pan and pressurised by the oil pump. The output from the oil pump is then filtered,
cooled and distributed through internal oil passages.
All moving parts are lubricated by pressure or splash oil. Pressurised oil is also provided for operation of the variable
valve timing units and the timing gear chain tensioners.
The oil returns to the oil pan under gravity. Large drain holes through the cylinder heads and cylinder block ensure the
quick return of the oil, reducing the volume of oil required and enabling an accurate check of the contents soon after the
engine stops.
System replenishment is through the oil filler cap on the bank 'B' camshaft cover.
With the exception of the pump, all oil system components are installed on the structural sump.
