<VV> Timesert removal

[Charles h. Sadek]

Jim, I have used both regular TimeSerts and Big Serts (acquired block with
bad  head stud hole..) and Helicoils. Call TimeSerts, and order only what
you need.  Pay attention to length for your thread length/hole depth. Take
your time and look at what you are doing. Do it by the book and it works!!
IF it looks like you need a bit of chamfer figure out how to do it.. To get
a failed one out, TimeSert will know how. I tend to think a left hand drill,
large easy out, temperature differential, etc. 
Good Luck
Chuck Sadek

Thank you Larry,
  I can return the heads and that is what I am thinking.
I'm sure I can get the insert out, not sure what condition the hole will be
in.
Jim

Hi Jim,
I recommend you call TimeSert for their advice.   They are the experts.
TimeSert also makes BigSerts, which can be sometimes used to repair a
botched insert.  I have used them on heads that have had a thread repair
fail.   BigSerts would be a last resort.   You will need to purchase a
BigSert insert kit and inserts.  Note: be careful of the insert tool as they
can break if you are not careful.   Also use oil on that tool as they
recommend.   Note also that the normal TimeSert insert tool can be used to
insert a BigSert and save you the cost of a $25 insert tool.   Same 3/8x16
thread and it will work.

Good luck,

Larry
