On the almost perfect GTD I seem to have been given, low mileage etc, there
was a leak from that plastic flange... turned out to be corrosion on the
head from stud to waterway. Stopped leak with unneccessarily purchased new
flange and actually by new 'o' ring and joint sealer.
I drive it once a month to keep the bugs off, but that's it.
