1KZTE Engine leaks?

[aidendr]

Hello,
I was wondering if anyone with a 1KZTE have addressed leaks similar to this one or if there are any gaskets in particular I should take a look at in regards to fixing this? It’s not a constant leak that gets worse.

That would be a valve cover gasket. Not too bad really, considering it is probably 20 + years old.
