I blew air down the top of block and it sounds like it is coming out around either the main or connecting rod bearings at #5 and #6. It also could be coming from the empty lifter bores because it had a hollow echo sound. I filled hole with oil and it just sat there. Blew more air trying to see where the oil goes and never saw it dripping other than the oil pump pickup screen then after a few seconds heard the same hollow sound as before around #5 and #6. I tried to feel where the air was going but couldn't feel nothing.
