When is a leak a leak -(Coolant)

Hello knowledgable people,

Ive a 3.9 RRC and have a slight coolant leak, its only noticeable when i stop and only leaves a 3 inch diameter wet patch. Not even noticeable in the header tank, but i think I've traced it to the inlet manifold area at the front just behind the Dizzy. Could this be correct and has anyone ever expirenced a coolant leak from the inlet manifold gasket or am i barking up the wrong tree?

Thanks

Rich

A photo pointing to the area may be helpful, but as the coolant flows into the manifold anything is possible, but as far as leaks... all my engine has had is one from the thermostat housing, and just a nip on the two screws of the housing stop it.

Many thanks, i'll nip up all intake and thermostat housing, fit the new drive belts and see how the leak is. To be honest its only a small leak so may not be worth the work to find it - until it gets worse
