Well it is either leaking or burning it, check for water in the oil (milk chocklate color).
The head could be cracked, some cracks will expand when hot.
One thing to check is after runnung the engine for a while, turn off, wait a minute and turn ign. on (don't start it). If coolant temp gauge goes up, then that indicateds a crack in the head, usually exhaust side.
