There is a bulletin for leaking head gaskets on these.
If a leak is found to be coming from a cylinder head gasket, the gasket must be replaced. When replacing the gasket be advised that larger flange hex head bolts are now to be used at locations 5 and 8. The larger flange hex bolts are the same as the ones used at the other six locations. When installing the two large flange hex head bolts at locations 5 and 8 a new style lower intake manifold gasket that has provisions to allow for the larger flange bolts must be used. These new lower intake manifold gaskets are contained in the gasket kits listed below.
