Cutting new oil collector slots in pistons

Went to see Richard today who designed my pistons. Showed him what the problem was that I am having at the moment, and he agreed to cut a new slot into the piston with drain holes, just under the oil ring, to get rid of oil that splashes onto the inside of the cylinder, especially the #3 and #4 cylinders as they are pointing down.
So that’s great news. The bad thing is that it means I need to pull the remaining 4 cylinders off as well…..
