A method for modifying a small diesel engine from a horizontal drive or crankshaft orientation into a vertical crankshaft orientation incorporates blocking of existing oil flow paths to rocker arms of the engine and replacement with pressurized low volume oil flow. In one form, tubing is added to direct oil from an oil pump onto the rocker arm mechanism. Additional tubing is then added to provide for oil drainage from the valve area to the oil reservoir in the engine crankcase.
