Cassius, look inside the underneath of the oil cap, if there is a milky white sludge in there it could mean a blown headgasket.
Although, some cars will do this if they only ever do very short trips, so its not a guarantee.
But if this is a case id get a compession test done on it, which is the only sure-fire way to know if its blown or not.
