on the way home i could smell some burning which i thought was the clutch as i was doing some quick gear changes.when i got back home though i lifted the bonnet and i could see some smoke not alot and hear a dripping noise i think i may have a leak with the coolant somewhere but not sure where and when i turned the engine off you could hear the pressure of the coolant going from the header tank to the main coolant and vice versa please tell me its just a small leak or a simple blocked pipe and nothing major.
