Valve cover, oil filter, oil press sending unit, oil filter adapter, rear main seal, oil pan gasket...... You kinda gotta get under there and start looking, then you can narrow it down. I'm assuming you're not losing that much oil, is that why its hard to find?

Check the valve cover gasket, cheap easy fix and fairly common place for a leak. Sometimes you can get away with just 'snugging' the bolts up. If you do need to replace go for the rubber gasket not cork and tighten the bolts to I think 7 ft lbs. Hope this helps. If you still cant find it, dont worry the leak will get worse over time then you'll find it for sure! LOL

If it's not at the rear of the valve cover then it's most likely your rear main seal.
