Using the UV dye let me find the origin (intake/head spot) and fix it.

I second Patrick's recommendation. I bought an inexpensive UV kit from Summit that came with dye for oil and coolant. I was able to verify that the oil leak that I had was not coming from the valve covers or intake. If you need more dye, you can buy it at Napa (PN 765-2661).
