High Oil Pressure - 1971 MG Midget

After putting the first 200 miles on a rebuilt 1275 engine in my 1971 Midget I’m trying to find the cause of high oil pressure. The car also smokes until the pressure drops down, once it’s warmed up. This is part one of hopefully only two videos on this subject. It’s too cold for working in an unheated garage, so part two will be a few months from now.
