So, I rebuilt my 3FE last spring, and lately I've been noticing more valve train noise than I'd like, so I pulled the valve cover, and to my horror, the valve train was pretty much dry, with a little oil on the back half (downhill side) of the head, but the front half had basically nothing but dried up oil. It's got a new Aisin oil pump and oil pressure looks good, and I checked to make sure the machine shop put the tower with the oil galley in the #4 position, so it should be getting oil. Is it possible some gunk got into the oil galley and isn't making it's way onto the valve rod to disperse? Suggestions?
