^^^^ Very true LOL!!! I've had water in my upper intake, lower intake, cyl's, and floor board..... I might have one of them boat cars, with holes in it....

Seriously though... sounds like you've done what's needed... is your radiator clogged at all (when car is at running temp you can put your hand on the radiator and feel for different temperature spots)? Do you still have heat? Do you appear to be losing coolant?
