First post, 3rd 4.4 V8 Bmw, 2 out of 3 blown/damaged . Most likely my last V8 BMW.... currently 13' M5 38k 6 speed stock ( production month was not needed for oil pump recall) Did Rod Bearings 1k ago.... decided to give 1 pull to almost 5k and the car died after the pull. Sounds like like the guide tensioner broke and spinning around hitting the walls. Had others come take a look it at they said similar things or valves. Car runs, holds oper temp, normal idol just Sound like metal on metal brake noise. FML I think it's times for S55.
