This engine uses a full pressure lubrication system which
delivers oil under pressure to crankshaft, camshaft,
connecting rod bearing surfaces, and hydraulic valve
lifters.
A high-ef
fi
ciency gerotor oil pump maintains high oil
fl
ow
and oil pressure, even at low speeds and high operating
temperatures. A pressure relief valve limits maximum
pressure of system. Closure plate must be removed to
service oil pickup, pressure relief valve, and oil pump.
