Has anyone put a bead of rtv around the gasket of the valve cover? I have a new valve cover and gasket and it has held up fine for about 500 miles. Then I recently just let the car sit for about 6 days and since then I can smell burning oil. I took a look and it appears it is leaking into downpipes. I am not sure if running higher boost would be causing any sort of issue? I was thinking about putting on some RTV to just help seal it a little better.
