The po of my car ran then let the car with an exhaust leak on the drivers side. I am doing battle with the manifold now. The last two studs over the engine mount did in fact break and were the cause of the leak. When I removed the manifold they were well rusted around, as well as between the two halves. Of course they broke just a little recessed of the face of the block. Upon inspecting the face of the manifold the last port where the studs broke were not in line with the other two faces but recessed about 1/16". I suspect the extra tension on the manifold caused the studs to break. The face was also badly pitted. Needless to say I had the face of the manifold ground to bring the faces all in line and eliminate most of the pitting and hopefully the tension. Stephen Vin 3601 "Typically it is not the fastener that fails, the gasket blows out........ the longer you drive with an exhaust leak the more trouble you will have with the fasteners and you may have to have the exhaust manifold "planed" or ground flat so it will make good contact with the cylinder head."
