The engine is equipped with force-feed lubrication.

gear at the flywheel end.

The oil pump draws the oil from the oil sump and delivers it through the oil cooler and oil filter to the
main distributor gallery and from there to the main bearings, big-end bearings and camshaft bearings
as well as to the small-end bearings and the rocker arms.
