Have been doing a little reading on some Ford forums. I think i understand how the pcv system works now. The breather i installed in the valve cover the other day which was clearly venting pressure should have been sucking air. For it not to be sucking but venting my pcv valve would not seem like it is working. Replaced with new pcv valve though....
With the engine running, and hose off pcv valve, I should have a strong vacuum--correct? Maybe not enough vacuum for the valve to work? I will try and do some more investigating tomorrow night.
Still wondering if the valve covers are the issue. When i checked the new pcv valve tonight there was oil residue in the hose going from the valve to the carb spacer.
