on a 2002 ex civic stock, i did a search and read that i could use them one more time before they need to be replaced with new ones.

does anyone know for sure?

 

Re-use them. just torque them to spec and you will be fine.

 

thanks. i heard that honda doesnt use streatch bolts. what ever that means.


i did a search and what i got was 49 ft/lb of tq.
is it 49ftlb tq?

 

The head bolts do stretch. The correct way is to measure the bolts for stretch and replace them if needed. Normally you can reuse them, especially if it's the first time they have been out.

Those bolts are set by torque angle, not a set torque amount.

edit:

oops, thinking of wrong engine, ignore that (had accord on the brain)

Ya, 49 lbs in three steps.

 

thanks good to know now.

 

Dude... When in doubt, throw them out.

If you don't know then just buy new ones. They are cheap.

 

what do they run for?

 

Dude... Call the stealership or check online... Last I checked, it was only a few bucks. I dont know exactly how much.

 

ive used mine like 10 times already

 

wow, serious?

 

Personally, I'd replace them with new studs.

They need to be bolted down, sequentially, in three different stages.
1. 14 lb-ft
2. 36 lb-ft
3. 49 lb-ft







Hm.. why are you having to rebuilt so often?

 

well ive used the same ones around 5 or 6 times

haha maybe cause i like to...but head bolts have never failed me

 

get new ones. Do you want to redo the work by not purchasing $100 worth of hardware?

 

Yes.

unless your an idiot you will realize it doesnt matter if it stretches, because when you torque them down, its based on the torque of the tigntening of them. Not the length of the bolts.



i reuse old head studs and never had a problem.


SO. there must be alot of suckers on here, who replaces the wheel studs every time they change their wheel? you stretch them i bet.

 

What you don't realize is that as the head bolts stretch, the metal gets weaker. The end result is a broken head bolt and a blown headgasket. This is especially important on a lot of Honda engines that are NOT set by a certain tourqe amount but by angle. And yes, wheel lugs also can stretch if over-torqued.

949, just reuse them, you will be fine.

 

thanks guys

 

just buy some new ones it will cost like $10-$20 at the dealership
