Hi,
Dumping the excess oil back down the filler neck might not be the best idea.
My engine is coil ignition so any overpressure oil going into the filler neck will meet the crankshaft as it spins around. I can not comment on Mag engines which have the filler neck in a different postion.
I have tapped the front right of the crankcase so that the oil squirts front to back along the right hand side of the crankcase below the arc of the crankshaft.
I use a 1/4 BSP banjo fitting which just fits between the front of the chassis and engine.
My in build engine project will use an adjustable valve in the original position and an oilpump which is a bolt in new one using the original oil galley as feed to the crankshaft as per the Speedy Pressure fed engine.
If you do not plug the front of the oil gallery oil will flow back to the oil jets unless they have been blanked off.
