The cylinder block uses bored cylinders as opposed to liners. In the event of cylinder damage or wear out, the
cylinders may be able to be repaired.
For engines displacing 6. 7 L, the cylinders can only be bored oversize once for the use of oversize pistons and rings (0.5 mm [0.020 in] oversize). A repair sleeve can not be installed if the cylinder bore must be bored more than 0.5 mm (0.020 in] oversize. See the Overbore section of this procedure.
