Before starting it for the first time after overhaul, Continental

Can anybody explain how is this achieved?


The easiest way is to pull the top plugs (bottom plugs if you're the type where things fall into open holes when they shouldn't). Then, spin the engine over with the starter, 30 seconds at a time with 2 minute pauses to allow the starter to cool, until you see pressure on the gauge.

When the engine was assembled the oil pump should have been packed with grease to aid priming. If not, and 4-5 iterations of cranking don't do it, try the following:

Put a plastic or rubber hose on the crankcase vent line. Remove the line from the oil pressure gauge port on the engine case. Blow as hard as you can (with your mouth, not shop air...) into the hose while cranking the engine over. Watch the oil pressure port closely. When you get oil in your eye, you're done.
