Here's another suggestion: if "pushing hard" means running at maximum RPM's, it might mean (assuming the oil pump pumps more at higher RPM's) that your oil return holes (where the oil drains back down into the crankcase) are partly plugged...that at lower RPM's the oil drains back down OK, but at maximum RPM's it piles up in the valve cover, coming out thru your leak.Cure: running wire down return holes with a little gas or cleaner, jiggling wire to loosen gunk. If you try this, change oil and filter, run for an hour or so and change again, in case more gunk comes down into pan. One more thing: if the oil gets high enough, it'll go down around the valves into the comustion chambers, it'll smoke, and most mechanics'l bet a months pay your rings are shot. (BTDT)
