I have heard about 460 oil pumps mounting boss cracking. Maybe that is the issue. Engine has a new Melling pump but it doesn't have a beefed up mounting boss like some do. Thanks for the Ford oil gage info. That is why the gage goes from zero to the same level each time. Sorry but the only way I can describe my feelings about this fake gage is Rat Bastards. There is still an issue just a different way to think about it. Looks like a tear down is in order. I was afraid that maybe I wiped out a second cam but there is no valve noise. If the cam was gone there would be valve noise all the time.
