noticed I was loosing coolant and engine running rough when starting cold. also check engine light came on with cyl 4 misfire. pulled plug with engine cold and noticed water on top of piston. head gasket needed to be replaced due to rust through. head bolts also need to be replaced at same time, they are not re-usable. this is a typical problem for this engine.
