Removal
Holes drilled in the crankshaft carry oil from the
crankshaft bearings to the connecting rod bearings. Pistons
and cylinder walls are lubricated by oil thrown off the
crankshaft and connecting rod splash. Piston pins are
lubricated by splash.
In the 231 engine a drilled hole in the camshaft
connects the front camshaft bearing journal to the front of
the camshaft. Oil flows from the journal through a passage
to an outlet between the camshaft sprocket and distributor
gear.
The oil stream strikes the distributor gear and provides
ample lubrication of the timing chain and sprockets by splash.
Each rocker arm and valve is supplied with oil through
the tubular push rod. This oil comes from the inside of the
lifter, passing around the metering valve and through a hole
in the lifter push rod seat. Oil from the push rod passes
through a hole in the rocker arm push rod seat, and emerges
on top of the push rod seat boss. See Fig. 6A3-6.
