The oil pump is driven by the distributor shaft, with an intermediate shaft in between. There is a plastic coupler between the oil pump shaft and intermediate shaft. You could take out the distributor and put an oil pump primer shaft down in there and spin it with a drill to see if it's all connected and working properly. If no oil pressure with a drill, the problem could be that the pickup tube has broken or fallen off the oil pump or the bolt that holds the oil pump to the rear main cap is loose (not common). The solution would be to remove the oil pan and replace the oil pump and pickup. If the engine ran without oil, you may need to check the condition of the bearings.
Your check valve is not holding in the oil pump and allowing the oil to fill the engine. When you start up, the oil pump is trying to empty the engine and excess is pumping out the breather or overflow.
