Consumer Description

Vehicle was idling rough. Would periodically accelerate without pressing the gas pedal. It would then go into limp mode. And display Services engine soon light. I took the valve cover off to inspect the camshafts and found the camshaft adjuster gear bolts were all loose. 5 of the 8 bolts were snapped off. 2 of the 5 missing bolt heads were found in the head of the engine 3 were found in the oil pan. If I did not discover the bolts were broken the timing chain could have slipped off causing an accident.
