95 Honda Civic EX 1.6 manual 2-door

While working on another problem, broken cylinder head cover bolt, a screw fell into the left bottom oil passage. A regular household, sharp pointed screw.
I broke the tip off a magnetic telescoping screwdriver and tied it to some fishing wire (all I had at the moment) and tried to get it out. I think I felt the magnetic tip contact the screw, but I could not get it out. After a little jiggling, because of the route of the passage, one immediate right and then another right, it cut the fishing wire. Later I got much more powerful magnet, tied to magnetic coil wire. I could not feel anything this time.

I've already tried draining the oil pan and used a powerful magnet to search around the outside of the pan to the hole. I think both pieces are stuck in the oil passage. The car seems to run fine - there are after all three other passages.

But short of taking out the entire cylinder head, does anyone have any other ideas?

Would taking the oil pan out give me better access?

Does this have any affect on the oil pressure? Or is this benign?

I plan to rebuild the engine after I put another 80K miles on it. Seems kind of a prohibitive to spend at least $500 on labor just for two bits of metal.

Thanks a bunch. Much appreciated.
