When installing a valve cover gasket, even if you install the helicoils to do it..don't overtighten the valve cover bolts. You will bend the lip of the valve cover every time. There is no real oil pressure under that valve cover. Oil just splashes around. Let the gasket and sealer do the job and no more than 8-10 pounds on the bolts. With a Nissan aluminum cover, the risk is more that you will crack a corner of the cover, though. Around the bolt holes. The lip bending is more for steel covers.

Ask me how I found this out a looong time ago.. Back in the late 70's I bent the lip on one steel cover so it always leaked. And I cracked the corner on a Nissan aluminum cover.
