And the saga ends! Not with a spectacular solution either.
Ran the car last week with 39 nozzles and an 84 pill. I made sure I rolled into the water box at 180 degrees. No oil spray on the runs. Too little heat was the problem.
I picked the vacuum pump RPM up to 75% instead of 50%. I think it was still building crankcase pressure because I had a small valve cover leak. I am going to leave the vac pump on and re-install my header evac system with check valves. Hopefully that cures the pressure buildup. Best run was 7.89 @ 169 mph. DA was 4500 feet.
I wanted to thank all you guys, especially Hammer, for trying hard to help me sort this out.
