buzzing sound from engine

Hey all

Well what a day, i was gonna take the d to work today but with white smoke pouring out the exhaust which seems to be like abit of damp in the engine, i did soak the car in water at the weekend, lol. Anyways while looking at it i heard what seemed to be like a buzzing noise coming from the top right quarter of the engine, only when the engine is running, it was getting quite load but couldnt pinpoint it. Anyone know what it might be?

Frequency valve. It's meant ot do that. Right hand rocker cover. Two hoses and a white plug.
