Default Blown valve cover gasket caused by pcv?

There was oil pooling under my car after running, got out to the sound of sizzling and smoke and smell of burnt oil. Clearly, my pcv valve has failed and I'm guessing caused a blown cover gasket. There was a slight collection of oil above the left head here. There seems to be a lot of grime on that side of the engine as well. Seems to have been a problem for a while. Ordered valve cover gasket and pcv valve. Is there anything else I should be looking for to replace in there?

You will require FIPG for application in certain areas of new valve cover gasket and cam wedges (half moon shaped plugs used to fill void

Before removing valve covers seriously clean them and surrounding area to prevent grit from falling into engine.

at back of head after head is machined for camshaft)...use Toyota 00295-00103

If unsure about any of this, check out a Lexus shop manual or hire an experienced wrench.
