If a head gasket goes out it will not always cause water and oil to mix and vice versa. It's possible for it to leak between cylinders, develop external leaks, or burn coolant or oil. What type of things have you been doing to the car that could cause a head gasket problem? Also have you pulled the spark plugs to see how they look? You can tell a lot by checking if they're oily, have rust on them, etc.
getting ready to drain coolant today and perform a compression test i'm fairly certain its the head gasket as its all the normal signs of it i was just so panic'd yesterday i started asking for help from everyone everyone that's had one go said mine sounds the exact same as when it happened to them
cause my car has been running extremely warm and i added some coolant but i suspect then along with a slight detonation problem due to a faulty regualtor i was using pushed it past the limits
