Dan-I did an exhaustive literature search through approx. one dozen books. I'm an open wheel racer/crew chief/engineer/mechanic, and utilized a bunch of references which I've acquired over the past 10 years. Normally racers use dry sump systems, but certain classes (showroom stock) must utilize the existing wet sump systems. Then I bought the following new stock Ford parts to examine them-Y2K pan; oil pick up assembly; upper baffle (windage tray). All reference material pointed me to 1 glaring problem-the windage tray. Ford designed this piece to do 3 jobs-scraper, girdle and windage tray. Unfortunately, it should have been 2 or 3 seperate parts. As I mentioned earlier, I'll have a fix for this problem shortly. I must get the pan off and examine the existing set up to be 100% sure of my design. Can you direct me to your database of problems? I'd like to know if these failures occur on Y2K models. I have a hunch that Ford changed the head gasket to limit top end oiling and keep more oil in the lower crankcase.
