The worst case would be a blocked coolant passage in the engine, causing a hot-spot and steam. Hope it's not that. I'm pretty sure that's the case with one of my engines that had a water pump impeller come apart. Easy driving, no problem. Hard driving on it loses coolant. Tank was replaced air purged, and leak checked. At least in my case, I never liked that engine anyway.
Do the pressure test as JFP suggested. That way, you will know if it is a true leak or an over-pressure problem.
