Found the smoking gun on my engine meltdown........fan hub got loose after alternator belt failed & wrapped around ground cable. Sudden jerk snapped one bolt & sheared dowel pin allowing the fan to wobble. Said wobble confused the injection system which has magnets in the fan--resulting in lean running at 80mph on interstate and frying the exhaust valves & seats.
Sooo....I'm looking for a good fan hub & spacer and at least one bolt.
