98 i30 is leaking oil. Valve Cover, oil pan?
 
Well it's oozing oil more than leaking I should say. Just a little spot on the passenger side every day. I know my valve cover has been slowly (but not enough to drip any) oozing as well, but I'm wondering if it is just that issue getting worse or if it could be leaking from the oil pan or another area. I can't pinpoint it. Anyone have any idea what it might be?

Could be the oil pressure switch. Those seem like they are key problems for leakage.

+1 to the pressure sensor.

Most of mine had camshaft position sensor switch o-ring leaks. A few front main seals.

To add to CS_AR's post, the camshaft position sensor is very easy to replace on these cars and it's only about $40

The valve cover gasket job is almost impossible. If you attempt it, get either Beck/Arnley or Victor Reinz gaskets. They are the OEM gaskets but cost much less than the dealer charges. Also replace the rear fuel injectors (and get the Hillman screws for them) and clean out the EGR tube while you're in there.

You could also try high mileage oil until you're ready and able to replace the gaskets.

It could always be that Upper Oil Pan....
