I am looking at installing a fresh water cooling system on a '90 OMC 2.3 Cobra. My first problem is my exhaust manifold has internal crack/s, which is leaking water in to cylinders 2&3. Will the coolant passage at the riser be blocked off where I can continue using the manifold that I currently have or will have to buy another manifold?-$$$$!!!!- Any advise on this conversion? Thanks, Bruce
