Valve Cover Gasket Question (yes, another)
Be sure to check that there’s no interference and that your valve covers are sitting as they should. When I changed from a single plane intake manifold to a dual plane I had the smallest oil leak that took some time to find where it was coming from. The dual plane intake was stopping the valve covers from fitting properly and I filed down a small notch on my covers. Right where the intake and valve cover meets you’ll see where I had to file it down.
As far as gaskets go I went with the Real Tennessee gasket and am leak free.
