The metal heater bypass hose section blew overheating engine and warping head. Had head gasket changed and head planed. Have changed plugs, wires, egr valve, cracked pcv hoses, repaired all visible vacuum hoses that were bad.
Am still experiencing rough idle and intermittent sessions of power loss accompanying check engine light signalling leaving errors mentioned above.
