Defect
On large buses, the tightening process for the lock nuts used to adjust intake and exhaust valve clearances is improper, leaving some lock nuts with insufficient torque. Continued operation allows these lock nuts to loosen and fall off. In the worst case, a lock nut may enter the engine and cause engine damage.
Corrective action
On all vehicles, inspect the lock nut tightening torque and retighten to the specified torque. If a lock nut has fallen off and cannot be located in the surrounding area, replace the engine with a new unit.
