Thanks for doing this, I purchased the engine off Shane and spoke to him about the issue some months ago, we have placed the modified sump with extra oil pickup line on etc and use his breather kit as well, I am going to try a few different things this weekend to see how we go. A local guy has sorted the issue by splitting the motor and basically putting a return line back into the top of the motor, this has sorted the problem but seems a drastic fix. I'll let you know how we go, thanks again.
