I asked if she had her receipt for the work and she said, "Yes, I dug it outta my car records and have it here" - so, I had her read the list of parts that were used and - sure enough - about halfway thru, she read, "Time-Serts".
Soooooo...........now I'm wondering what kinda can-o-worms I'm about to open up!! Can the larger inserts ("Big-Serts" or "Norm's") or the studs still be used? I'm scared!! I guess the only way to know for sure is to get this POS apart and have a look-see (I got a late start today, due to illness).

One thing to keep in mind is that IF this was a warranty job, GM will only authorize Timeserting holes with pulled threads as opposed to all 20 (the proper way). So it's entirely possible that it may only have one or two bolt holes Timeserted. The other possibility is that they either did not hold or should never have been done in the first place (see the "Root Cause" Sticky in the Northstar forum).
No sense posting two identical threads on the same problem in two different forums - the jumping around accomplishes nothing. This thread is not specifically germane to Deville - so here it sits in Northstar.
I agree completely - but, of course, I had no way of moving it myself, lol! THANX for consolidating everything........and SORRY for posting in the wrong section.
Ranger - The previous job was apparently done by an independent shop - not as a warranty repair by GM - so, short of calling my friend back to see how many inserts were used, I won't know until I get it apart.
Anyway, I'll be back at it tomorrow morning (very little got done today, due to illness) and - hopefully - have the heads off by the afternoon and able to see how the block holes look!
I can't really recall exactly (it's been so long since we've don't a warranty HG repair)
but we would probably have found all 20 holes to have need for drilling/tapping/inserting and GM would have no problem paying for the full job
i doubt they ever asked for any blocks back as cores for the sole purpose of catching a dealer inserting 20 holes when they should have only done 4
