The problem is the engine was overheated by a friend when a heater hose let loose.
I can't imagine your reaction when you found out a "friend" allowed your V12 to overheat!
What was it he/she, missed along the way, the temp gauge pinned, the funny smoke coming off the engine, or trailing the car, or was it funny noises that finally won the day...???
Geez, sorry to see something as unnecessary as this happen to anyone, especially a V-12 Benz, I hope your friend took some responsibility..
I hope others reading your post take note. To see a fine old car like this get parted out because of a heater hose is... well you get the point
I have a 30 year old, 34 ft Twin inboard (350 Merc's), Silveton Flybridge cruiser which I take on fairly long trips. I change all the hoses and belts every 3 years without fail. Overkill?, probably, but I can say that I have never been stranded, broke down, or ruined an engine because of a failed hose or belt..
Hmm wonder what a pair of V-12's would do for the old Silverton??...
Anyway, hope your able to replace your benz with another nice one..
I see a new post above where this "guy" wants to swap a Benz for a golf vacation at Pebble Beach, and I think his wife may be a part of the bargin...
Just a thought..
