Oil was drained and two quarts put it at the top petcock.
The engine runs, I wanted to verify the level prior to starting it again.
Between the oil pan mounting flange and the block is a solid "restriction" plate with two drain holes, front and rear, to allow oil back to the pan and four dimples for rod bearing dippers to collect oil.
Oil is supplied to the front and rear main bearing journals via side mounted oil pump and external copper tubing.
Yes this is a Continental engine used in numerous applications.
