Thanks for the pointers! The smoke seems to be whitish/blue. It doesnt seem to smell like burnt oil, but the coolant level (even though it only ran for a few minutes) seems to be staying put. It increases as the engine temp increases and is considerably more when revved. I should also note that the plate that blocks off the exhaust (not sure of the name) that has some sort of preload spring running behind the manifold and half-moon (counter weight??) toward the front of the vehicle is stuck in position (not sure if open, closed, or somewhere in between).
