I think the olm is a good guide to use as a reference but if you have a vehicle like these DI 3.6 and they're known for timing chain failure and gm themselves recalibrated the olm because they were over optimistic and you still don't take the safe road and change it somewhat sooner than the olm says...well you're asking for trouble Bud.
