One thing in advance: You have a damn great website here! There are certainly lovers of other vehicles who would like to have such a thing for their sweetheart.
I have a question about leaks in central hydraulics. The oil has spread well over the underside of the vehicle, I suspect the leak below the balancing tank, as the hoses are already wet there. What is likely to expect me there? A crack in the balance tank? Loose hose clamps?
As the problem seems to have occurred more often (but unfortunately I don't have a precise description of the problem). I thought it might be smart to ask here before I fry it all up.

Thank you in advance!
Edit: The hydraulic oil is reddish, shouldn't it actually be green?
