I know you have not lost water and the oil looks good. Odors? Temp?

That looks like white smoke to me but I was not there. If it was white and not black we can rule out the PCV valve.
Have you tried duplicating this at high rpm on a level surface both with and without a load or does it ONLY happen at an angle?

no real odors that i could tell, as for duplicating it...i never got on it while i was just driving around, the only times i hit the skinny pedal was at an incline

i removed the grommet and PCV and there was some oil residue on the grommet, but no oil in the PCV or the hose to the PCV. I havent pulled any plugs yet...might try that later tonight

We need to try and duplicate it on level ground. Check the PCV just to make sure. if you do have a head gasket leak at the rim of the cylinder and the PCV is bad, it could be pulling water directly into the cylinder and not even messing with the oil. A failed PCV usually produces black smoke but in a head gasket situation it just makes the existing leak worse by pulling more water via the negative pressure. Did you shake the PCV to see if the check vavle is free and rattles inside.
Napa sells the coolant tester for $50.00.

Chuck, are you running fuel injection? Automatic or manual transmission?

The other thing that concerns me is that it is only happening, so far, under load. I would venture to say, smoke color aside, that a cylinder compression test may be prudent just in case you have a ring going bad. Since you dont have true dual exhaust and cant duplicate the conditions we cant really narrow to which side this may be originating so test all 8. Have you looked at the spark plugs? I have a compression tester at home if you need it but I bet you have one too.
My bets are on head gasket or ring.
