When the treads are cleaned and they show no signs of damage you will be good.Boy...I suppose that AJ is the expert on this (being a Cadillac technician), but I do want to point out that there have been REPEATED experiences by members on this board and another board where they didn't Timesert all the holes and the problem has returned. In the past, it was best practice to Timesert all 20 head bolt holes and you knew you were good for another quarter million miles.
Here's why he's trying to avoid them.mikeylok13; said:If i don t have a striped hole i could be ok using new bolts without time serts
because budget really tight .sorry about grammar punctuation.
I guess I just don't see what you have to gain by NOT using the Timeserts. Surely a Timeserted hole is not more likely to fail than an already possibly compromised hole.
If you are not on the Norm's insert band wagon or you are at a dealer that has not used them yet. You would have possibly ruined the block for another repair. If the block has time serts in it and then head gaskets fail a second time you are screwed because you know that the inserts pulled free every time.Exactly. Why would you not do it when you're that far into the project?
LOLBlock #2 is in perfect shape and needs no inserts, but you put them in because you can. Now the head gasket pops at 70k and the engine is JUNK.
You really don't understand that it is just making the bolt bigger. It is not part of the block it is part of the bolt.:rant2:LOL
A timesert repair is stronger than the existing threads. Period.
If a block in "perfect shape" with timeserts blows in 6k, it would have blown in 100 miles without the timeserts.
