Hi Bob
Well I was pretty much right about running 235 without the valve cover in place. When out lifted the cover off the 235 on the engine test stand and hit the starter. At 400-500 RPM no splash no drips but at 1400 RPM a few drops of oil start coming out and landing on the manifold.
Added some higher resolution video of the 235 engine running topless.
