m. Lubrication.

The gear train is lubricated by overflow oil from the camshaft and balance shaft pockets spilling into the

gear train compartment. A certain amount of oil also spills into the gear train compartment from the camshaft

and balance shaft end bearings, and idler gear bearings. The blower drive gear bearing is lubricated through

an external pipe leading from the main cylinder block oil gallery to the gear hub bearing support. The idler gear

bearing is pressure lubricated by oil passages in the idler gear hub which connect to the oil gallery in the

cylinder block.
