Default Slow Oil Leak 2003 IS300

Hey everyone, I'm rather new here. So I have a slow leak and not sure where it's originating from. I snapped a few pictures with the top timing belt cover off. I can't really tell if it's leaking from the valve cover or the crank/cam seals. There was dried up oil all over the inside of the top timing belt cover.

Your pics aren't working for one. Since it's been leaking for sometime based on what you say, get some degreaser and clean it up nice and shiny. Put the cover back on and drive for a few days. Take the cover back off and I'll bet you'll spot your leak.

Do you use a funnel to fill oil? I noticed a lot of the oil drip i have is from missing the hole. I do seem to also have a valve cover gasket leak though.
