Yeah, I too have a quail and it doesn't leak a drop. Don't run pressure but in the spring I always top off the radiator with antifreeze and it spews out some out the overflow until the level is right so if the cap wasn't quite well sealed wouldn't it leak then? I can't see any reason to run a pressurized system. What would be the advantage? If my engine is over temp,(boiling) I would want to know. If you like to keep the radiator completely full do like 1931flamingo does and connect a hose from overflow to a tank. Not trying to be contrary just wondering what the reasoning is? I know the OP was talking about a sealed system, not pressurized.
