Hello John. My name is Tan.I'm assuming this is a V8 they didn't make a 160 or a 260. They have a 165 which is an inline 6 and the V8 which is a 245.Remove the intake manifold inspect the heads and the intake for cracks. If no cracks are visible then replace the gaskets and reassemble.The possible cause is a cracked or rotted out cylinder head. The only water passage in this are is in the cylinder head it self.
