The five ring pistons are the only ones offered in oversize.(3) Liner projection (height of liner above face of cylinder block) ... 0.71 to 0.94 mm (.028 to .037 in)(4) Diameter of bore in cylinder block for liner ... 103.162 to 103.188 mm (4.0615 to 4.0625 in)Flanged Liners
New cylinder blocks have been introduced on 4.236 and T4.236 engin s. They have a larger cylinder liner parent bore diameter and the outside diameter of the cylinder liner is also larger. The liners will no longer have a flame ring. Effective with this change, only flanged liners will be available. The change became effective at engine serial number LD or LJ----- U106654N and up.
