I have TimeSerted many thing over the years. On a Northstar Block the Drill/Ream is centered with a jig and then the drill goes down into the bore about 3" before it drills out the threads. This would mean that it is pretty well centered! Yeah right. The block was square at one time also.
Do you understand that?
OK the block goes through heat cycles and the bolt holes become slightly curved.
When the drill gets to the bottom it drills ever so slightly off center. Maybe it goes towards the soft stuff. That would a good thing. Just think about this you have a drill in a 1" collar square to the deck and then it goes into a bore another 3". That means that it is held centered and square by a 4" tube. So why is it that I see so many off center? They hold up, but I just saying. So if one of the 20 hole is not perfect then the block is junk after the TimeSerts have been installed and they fail. If you just fix the bad ones and 75K later a different one fails you can fix the ones needed.
