Roy is right. I had a friend years ago who had some plastic all clear valve covers on a Chevy. You caint see nuthin. And he had a stock oil pump. Imagine how much oil a high volume pump would throw up there.
I made a clear top valley cover, and had it on my 505 for a while. it worked good, could still see pretty well w/ the engine running. but I tried to wipe it of w/ b12 chemtool and ruined it. will make another one of these days .
