Priming the oil pump prior to start up after a rebuild very important . Using the chain oiler union T 29 and a fuel line connector pipe assembly A68 AS and a 6 inch length of fuel line one can connect up to the oil entry directly into the pump port . Fill the hose with oil and rotate the motor watching that the oil is drawn in , do this several times adding more oil . A dry pump won't work .
When changing the oil , draining off the old stuff and having refilled the oil tank with 2 or more fresh quarts . With a pan beneath and the banjo bolt only screwed in a turn or so watch for the arrival of the oil at the bottom of the hose . First will come air bubbles driving out the old dirty oil , this to be caught in the pan . Only when the fresh clean oil arrives should you run in the banjo bolt , not before , ensuring the good stuff enters the pump .
And pour into the two center rocker openings via a squirt gun about half a qt. , this flowing down the pushrod tubes and flushing over the cams and rockers etc . Dry starts are a bad idea . This oil will flow down into the sump and hasten the pumps return flow arrival to flow quicker across the overhead rockers , etc . Be sure also to fill the filter chamber via the forward long rocker bolt A 22/1 in the timing cover , this speeds up delivery to the timing chest contents and through the delivery quill into the big end .
The total volume of oil will be around 3&1/2 quarts , watch after delivery is normal with some air bubbles mixed in that you do not overfill as this causes a mess ! Sid .
