Lubrication System
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-effi 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. Oil pan must be removed to service oil
pickup, pressure relief valve, and oil pump.
