Antifreeze will smell when it burns. Pure white is steam. Light gray is
oil. Black is fuel.
Again before you start it next time pull the plugs and check them. If they look ok spin the engine over without the plugs and see what shoots out the plug holes. If you find a wet plug or water shoots out of one of the holes you will know you have a water leak. Any water on the end cylinders could be intake problems. Any from the center are going to be head gasket or bigger problems.
Same goes for
oil. If the intake leaks
oil into the cylinders you should have a pretty even pattern as most intake gaskets will draw oil on one whole side when they go bad. The aftermarket "Race" style are the worse. The heavy paper, kind of like a cheap header gasket, will draw oil right thru the paper till the silicon seal fails.
Again the best and fastest way to figure it out would be to pull the plugs.
