    Hello fellow V12 enthusiasts,
    we are all aware of the "big" water hose under the intake which can lead to catastrophic failure.
    In my case the cause of leakage was a very less obvious one... UNDER the big hose there is a small one, a little more than two inches in length. Seen from above it appeared okay - only using an inspection mirror from the underside we could see it was starting to rip. (And rather sooner than later would have lead to the same catastrophic failure as the big one.)
    So I advice you whenever the intake is off the engine change this small hose also. It is a 15$ part.

    Enjoy your V12s!
    Regards Stefan
