Right, ive just noticed that my car has a leak, its the coolant for sure, cos i can see the colour of the anti freeze in it! Thing is, its not a big leak (well not so that i can see its losing water in the header tank), and only seems to leak very little when the car is running. The place where it is coming from seems to be underneath this blue thing on the side of the head lol (ive pointed to it in the pic).



Any ideas at all? Is there a gasket that could have gone where this part sits? or is there a chance the head is cracked??
