Default Valve cover leaking oil

Hey CL members I need help with my 98 GS300. I have an oil leak that's built up along the top of my exhaust header on the cylinder head. The oil seems to be dripping onto the timing belt and leaking through the cover on there. My question is aside from the valve cover gasket what other gaskets am I looking to replace along with it and hopefully end the horrible leak. Thank you for your time in advance.

If it's leaking inside the timing belt cover, prepare to change the camshaft seal and/or vvti gear seal. the camshaft seal is leaking, you might as well do the whole timing belt.

The belt was done by previous owner 30k ago but I'm assuming that in order to replace the cam seals the timing belt has to come off or be loosened as well?
