Looks like you may need a new gasket.

Welcome to the forum.
And I believe Honda just calls for gasket sealer on that entire surface. Don’t know if you can get those valve covers off of yours without pulling the engine… This job can open up a whole can of worms, so get the factory manual from here, if you haven’t already, and do it by the book for the hydraulic tappets and setting the cam lifter assemblies. Many mechanics go wrong here…Looks like you may need a new gasket.
