If they get clogged water can't get out of the plenum chamber. I'm not sure how thin the actual drain hose is, so I don't know if you can push the screw through the drain with something thin, long, and flexible. Maybe you can stick a magnetic pick-up probe dow the drain valve? With a little luck you can fish the screw out.

I lost one of my ECU screws there over a year ago. Never found it.

If it ever blows up my engine, I'll be sure to let you know :-)

i've dropped plenty of screws into my engine bay. they usually end up on the plastic pan at the bottom. try the magnet or try popping the plastic piece off.
