With the engine cold soak it down with something like simple green and hose it all down, do it a few times so its nice and clean. Then just keep a eye on it and see where the oil is leaking from. And since its leaking oil make sure to keep a eye on the oil level.

When I desludged my engine w/ Seafoam & switched to Synthetic when I bought it, I developed 2 or 3 small leaks. I just tightened the valve covers & oil pan to spec and in proper order and haven't had a problem since. And a clean engine is a happy engine!

is it ok to spray that simple green stuff on electrical things on the engine or not?

The air intake manifold thu the brake booster Vac hose (for fuel injected) & gas tank is to clean deposits in the combustion chambers also.

the valve cover gaskets are known for leaking on these straight sixes, it really isnt that bad to change it.
