Agree with both jgold and skyline.... When the oil filter housing started to leak, I had no idea where it was coming from. The oil pan was completely covered and thought that was the problem too.. But when I took it to the shop, the mechanic told me considering the mileage on my car (140k) it's probably safe to look closely at the oil filter housing and also do the ccv... He cleaned it up and told me to drive around for a bit and come back in the afternoon. Then he called me back saying it was the oil filter housing gasket, so got both those done. He showed me the gasket that he took out and it was in 1000 pieces, it was real brittle.... Hopefully you can diagnose it quick..
