Another vote for oil filter housing gasket. I had similar leaks and after replacing that gasket I've been clean ever since. I believe that to be the greatest source of all the oil on the driver's side of the block leaking to the underside. I also replaced my CCV and all related hose around the same time and noticed some seeping on the hose draining from the CCV to the dipstick and oil residue on my driver's side motor mount. So it could be a combo, but start with OFHG, clean everything with degreaser, and monitor for further leaks.
