Me? Replacing exhaust manifold gaskets on the 77 Deville. The center manifold bolts have locking tabs to keep the bolts secure. The outermost 2 bolts at the front and rear of the head? No locks on those. The rearmost bolt on the driver said was loosening itself over many years and eventually deteriorated the gasket. Tried tightening up the bolt and it did not quiet down the exhaust leak. So, in goes new gaskets!
