Any leak in your coolant system (like a leak in the radiator cap) can make your car run hot. Liguids boil at a higher temp. when under pressure. Your coolant system when tight is under pressure. If you have a leak somewhere it is under less or no pressure causing the coolant to boil and not do it's job.
Running hot will cause, among other things, bhg's.
Change the cap NOW.
