I've done the research and from what I have found these should be torqued to 7 ft/lbs. But, is that for the smaller breather covers on top and the valve covers that sit on the heads?

I've got a film of oil between the valve covers and the heads (around the spark plug area). 36,000 miles and never re-tightened, so I'm going to try re-torquing before taking them off and applying new sealant.
