Me again...
Just for yucks I pulled the BobG radiator and put the OEM uni back in. While the OEM radiator and fan still work real well, I'm still getting air in the system.
The air enters WHILE I'm driving and not after a cooling cycle. I cannot find any coolant leaks or drips under the car ever. Haven't pressure tested recently but did when first encountering this issue over a year ago and the system held. When I swapped the radiator, I drained the coolant and no oil/crud in it -- was very clean.
Hussein: Can you show me where the vent is located on the water pump? Diagram or photo would be helpful. I'd like to plug mine and see if that solves the problem. If not, I'll probably try the UV dye test...

There is also a vent/valve in the underside of the water pump (on my AC equipped version). I know this, 'cos when using Evans Waterless it has to be filled with silicone to prevent air being sucked in....
