Hi all i have a leek from the top middle left hand exhaust manifold on a marine 3208 cat inboard .
itt appears to run down the top of the manifold and drip from the bottom end flange to the turbo tube.
i can't see any reason why this would happen as it runs cool around 70-80 degrees and there appears to be nothing higher leaking onto it .
Has anybody had a similar problem as I thought that the manifolds being cooled use sea water from the alternative cooling system through the heat exchanger.
are there any bolts that could be the problem or is it possible that the manifold has rusted through
it is definitely coolant as it drains into the bilge and from the coolant system
any ides about there would be of great asistance
