1996 Ford Taurus Sho

I HAVE A1996 FORD TAURUS SHO V-8,IT JUST TURNED 80,000 MILES AND HAS HAD ALL REGULAR SERVICE AND NOW THE CAMSHAFT GEAR HAS FAILED ON THE CAMSHAFT AND DAMAGED THE ENGINE!I WORK AT A FORD DEALER AND SEE THIS ENGINE FAILURE OFTEN. IT SEEMS THAT THIS IS COMMON ON THE V-8 SHO ENGINE AROUND 75,000-85,000 MILES AND SOMETIMES THERE IS A TICKING NOISE THAT IS CONSIDERED A WARNING SIGN TOO GET REPAIRS BUT THERE WAS NOT ANY WARNING FROM MY ENGINE. I HAVE DONE ALL KINDS OF RESEARCH AND FOUND THAT THERE ARE LAWSUITS AND NUMEROUS COMPLAINTS AND BLOGS DEVOTED TO THIS EXACT ISSUE BUT I DON,T HAVE ANY INFORMATION AVAILABLE FOR ASSISTANCE ON THESE VERY EXPENSIVE REPAIRS THAT ARE DEFINITELY DUE TO A DESIGN FLAW AND I HAVE 18 FORD TECHNICIANS THAT ARE FACTORY TRAINED TOO BACK THIS UP!I DID NOT BUY THIS VEHICLE NEW SO I CAN,T SAY IT WAS NEVER ABUSED BUT AFTER PARTIALLY DISASSEMBLING THE ENGINE SO FAR IT IS CLEAR THAT IT WAS VERY WELL MAINTAINED AND CARED FOR (IT LOOKS BRAND NEW INSIDE)THERE IS ZERO SLUDGE AND CAMS AND FOLLOWERS ARE SPOTLESS. I WILL NEED TO PULL THE REAR HEAD AND SEND TO MACHINE SHOP FOR EXHAUST VALVE REPLACEMENT AND DEPENDING ON HOW MUCH DAMAGE MAYBE GUIDES AS WELL. I AM VERY CURIOUS AS TOO HOW MANY OF THESE ENGINE FAILURES ARE ALWAYS ONLY THE REAR HEAD EXHAUST CAMSHAFT BECAUSE SO FAR ALL I HAVE SEEN IS THE REAR EXHAUST CAMSHAFT GEAR FAILURE AND THAT IS A F- IN MY GRADE BOOK! *TR
