engine oil reservoir. Oil pan is attached to block and
sealed with a gasket. The oil pickup tube has a
strainer and cover.

cylinder block. Oil pickup, pump and check valve pro-
vide oil flow to the main oil gallery.
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.
