Thanks 'remoak' & 'tankengine' I didn't want to go too deep with all this but I think GG might now understand what we are trying to talk about here. Filling an engine completely with oil would take an extraordinary effort inc blocking off the exhaust system & the intake manifold/s:-) Just filling the engine 'till oil overflowed out of the filler point only means no more can drain down into the sump, the bores would be mostly M/T.

The bores do fill with oil.
How do I know? Because I've done it plenty of times. Don't be an armchair expert until you have tried it.
When you remove the spark plugs and turn the engine over, oil pumps out of the spark plug holes with much enthusiasm.
Try it
