I have a water leak on my cossie, thought it was the head gasket but now believe it is a pipe under where the injectors are. Right hand side of block somewhere round the oil filter area. Does anyone know if this is a bugger to get to, i'm not very good at mechanics, is it best to take it to a garage, don;t really want to drive it whilst it's pissin out. is it easy to fit and what the pipe is called (part no if poss)

Your help and advice and instructions on replacement of this pipe would be very useful and appreciated!!

Thanks Bison (Newbie)
