DESCRIPTION AND OPERATION (Continued)
ENGINE LUBRICATION SYSTEM
PRESSURE LUBRICATION
Oil drawn up through the pickup tube is pressur-
ized by the pump and routed through the full flow fil-
ter (Fig. 2) to the main oil gallery running the length
of the cylinder block. A cylinder head restrictor,
located in the block, provides increased oil flow to the
main oil gallery (Fig. 3).
MAIN/ROD BEARINGS
A diagonal hole in each bulkhead feeds oil to each
main bearing. Drilled passages within the crankshaft
route oil from main bearing journals to connecting
rod journals.
CAMSHAFT/HYDRAULIC LASH ADJUSTERS
A vertical hole at the number five bulkhead routes
pressurized oil through a restrictor up past a cylin-
der head bolt to an oil gallery running the length of
the cylinder head. The camshaft journals are par-
tially slotted to allow a predetermined amount of
pressurized oil to pass into the bearing cap cavities
with small holes directed to spray lubricate the cam-
shaft lobes.
