Yes. Sometimes when the bolt fails, the IMS bearing can move off axis, timing chain(s) jump, and you get piston to valve contact related failure. The IMS bearing itself is still relatively OK except for the bolt failure. Other times, the bearing itself is tearing up, possibly causing the bolt failure; so it can go either way.
