Head bolts stripped

**Orrin's Z** · 08-09-2009, 10:59 AM

i was following the chiltons reinstall instuctions after replacing the head gasket and i start to torq down the damn thing kept spinning.

So thank you to the original owner for over torqing the headbots so there 8 in total that need to be repaired

all of the short 11mm bolts and four of the long. i found this kit called a timesirt but the kit is $500

i have the ability to get Helicoils for cheep. but i dont know how to install them.

So my question is what is the best way to fix this block?

I am really geting frustrated with this motor

I have checked the casting numbers and it is a LS6 block.

were you trying to reuse the old head bolts? They're torque to yield so therefore a one time use bolt.

i knew they where throw away bolts. i purchased new headbolts with new gaskets

Search on E-Bay for this number J-42385-100
I found a set for $120

Helicoils are not the way to go

For block head bolt thread repair
Timesert = good
Helicoil = bad

Agree! Most helicoil sets dont come with deep enough thread stock. Meaning they are'nt near long enough to cover enough of the threads on the bolt to be safe.. Usually they are no more than 3/4 in. thread coverage dont know if that's enough "bite" on the head bolt threads proly not...

Ps. Just wondering, if ya remembered to clear the bolt holes with compressed air before you started ?

when i drained the motor i turned it upside down to clear the holes of fluids and i was planing on geting a compressor or some more caned air to clear the holes
