Thanks for the info about Mr Hill. What was Mr hill's purpose of the excersize? Was it the need to reduce the amount of oil thrown out via the exhaust so that the fuel tank size could hold more fuel (distance)? Re bringing the oil to the front of the engine. I agree this would be better but the system now should be no worse that the original "blowby oiling" which seemed to work OK - the engine has many gallons of regular glo fuel thru it without any bearing or valve train problems.
