Re: G28T center cam bearing oiling?
I've never done a G-28, but have pressurized many B blocks. I didn't realize the pump didn't exhaust like on a B. A small amount of oil will go thru the upper bearing of the pump, maybe enough? Is there a hole in the galley to that brg.? You could file a very small flat on the upper end of the pump if you think it necessary. There must be a way, put in at the factory, those engines lasted a long time. I ground a cam for one years ago and was surprised the original cam had the Model A profile, not the B. This engine was out of a farm machine of some sort so maybe they did the cam to have the torque curve where they wanted it???
