I'm new to this forum, and was surprised to find that nothing came up when I did a search on windage trays. I'm interested in them because if I decide to replace the rod bearings on my 1992 Porsche 968, I may go ahead and install one while I have everything apart. So, I was wondering if someone could provide an explanation of exactly what a windage tray does, how it works, how it's differnt from a crank scraper, and how (as some manufacturers claim) it can reduce oil temperature. Thanks.
