I replaced the plugs, found oil. Figured it was the valve cover gasket since I knew that was leaking outside. Replaced it and the grommet seal. Next day it is smoking and more oil. I was told the valve seal...

When you buy the valve cover set, it will include the spark plug well "O" rings. Simply remove the valve cover and on the underside of the valve cover, you'll see the "O" rings that need replaced and you'll see exactly how the valve cover gasket itself fits.

I would try snugging down all the valve cover bolts before replacing anything. A valve cover gasket kit should have the grommets and gaskets necessary to repair this if you find no loose bolts.

Yes, you need a Rocker cover (valve cover) Gasket kit. Remove the valve cover, remove all old O-rings and cover gasket, clean grooves and mating surfaces without gouging or scratching them, put the new gaskets on as per factory recommendations, tighten to the proper torque and you're done. The spark plug holes in the cover are part of the valve cover gasket kit. Any Napa, Car Quest, Pep Boys, Auto Zone will have it.
