There's more than enough oil throwing around in there to lube cylinder walls, the oil rings are working their butts off trying to keep it low as it is. Entire motor lower end interior is pretty much oil fogged at higher rpm.

The stock aluminum zetec mid section is an attempt at a windage tray, although good ones are semisolid (screened usually) rather than solid. Solid tray simply bounces off thrown off oil back into the rotating mass again. Good windage pans have a kickout on one side to catch, strip away, and hold oil to allow it to flow down into pan lower. Trays help direct oil to the kickout. Scraper is on that side too. Using a scraper can often reduce the amount of small metal bits or flakes from normal running that get stuck in lower piston skirts.
