Aaaaand it gets better. So I always wondered why the right front corner of the engine was very oily. Tightening the valve cover nuts only helped a little. The #3 spark plug was always getting oiled on and I suspected the gasket. So when I put the offending lifter back in and before I replaced the valley pan, I removed the spark plugs and cranked the engine to see if all was well. BUGGER!! The #3 intake valve push rod was geyser-ing oil everywhere! Then it hit me- unregulated oil pressure at that damn lifter. I took out the #1 lifter and took it apart. I compared it to the #3 and sure enough the #3 was missing the metering disc. It must have gotten away and fallen down inside the oil pan. It's been awhile since I took apart a lifter so I didn't notice it not being there. That explains the oily side. It was seeing the full 60lb oil pump pressure smashing against the top of the valve cover and dripping out the side. Lovely. Add a new lifter to the ever growing list.
