I have 1973 Cadillac Sedan Seville. I still have a major exhaust leak, it is a hole at the top of the block right below the vavle cover. Any one Kw Wat it is or called??
Did your exhaust manifold rust through?? How are you getting an exhaust leak there?
Better definition is needed. It is probably your exhaust manifold as Mark said. Could be a rust through or could be a blown gasket with the age of the car.
