oiling · FF-0315

Why is oil drainage a problem on the exhaust side of an ARDUN conversion?

In the block, the old exhaust ports still run out to the side. Oil running down an exhaust push rod hole would go through the port and onto the ground. Steve says one accepted fix is to let it run through the passage and put a plate over each exhaust port with a line to the oil pan, sometimes joined into fewer lines.
