Tty bolts reuse is like recycling toilet paper. You could do it, but it will probably make a nasty mess.

Hi Guys,

I was doing heads and cam on a car as well. (ls3)
When I was done torquing the first sequence (22lb ft) I turned around to get my degree wrench for the second sequence (90*) and there I see my lifter guide bolts, so obviously that head comes back of.

reuse gasket? after what I read here that could be possible, but what about the bolts that have been torqued to 22lb/ft?

Yup you can reuse everything, just look close at ghe head gasket and make sure the coating isn't tore/ scratched on it... if it is then spray alittle copper spray on it and throw it back together!

The head gasket looks ok, and if people re-use it even after fully torqueing the head down I should be fine.

Still in doubt over the headbolts though, even though they were only torqued to 22lb/ft, the car get's a blower also.
Can they handle the power?

Since I am in Europe and need to wait 2 weeks for new headbolts, it makes it a hard decision. Otherwise I would have bought new ones allready.

22lbs is really nothing on those bolts. They wont stretch till much later in the torque sequence.

mark21742

I agree with this.

If your going with a blower, you should probably look at getting ARP bolts eventually

I think this pretty much says it all. Tourque To YEILD. The bolt has been stretched to the point of no return.
I have known a lot of people that cut corners and get away with it. I'm not one of those guys.
New bolts and gaskets on mine. If for no other reason, then peice of mind.
Just my 2 cents.

LoL,

if you think a head bolt has even began thinking about stretching at all with 22lb's, I have some oceanfront property for sale here in TN i'd like to sale to you!

However, in a boosted App, you're crazy for even thinking about using anything but ARP studs. They are just too cheap these days not too.

Your stupid if you take that big of a risk over a $30 part, just replace the damn gasket. And for the guy suggesting to re-use the head bolts, please stop suggesting dumb **** on a public forum, you can act as dumb as you like but getting on here and trying to convince others to follow your dumbass lead is wrong.

Would I ever reuse TTY head bolts- NO, not worth it IMO. Wouldn't reuse a head gasket either.

However, my dad had a problem with a car at the GM dealer that the engineers never heard of so one stopped by to check the car out. Anyways, he got to talking with my dad and was saying that the TTY head bolts are actually designed to be reused a few times. However, since they would have no idea of knowing how many times the bolts were reused, they always say to replace them in the repair instructions. Anyways, not sure how true that is but the guy worked directly with the TTY bolts so I'm sure he wasn't making it up. That being said, it is just not worth the chance of breaking a head bolt in the block lol

Um if the bolts are tty, and they are made to be torqued to 90ft lbs, and he only torqued them to 22 ft lbs then that means they are nowhere near their stretch point....don't jump on here and state calling people dumbass when you your self apparently don't know what you are talking about

Umm I was not even referring to the siruation where he tqed the bolts to 22ftlbs, I was talking about re-using head bolts in general. If you would take the time to read the thread you would see that it was suggested to reuse head bolts after they had been fully tqed. But that would take to much time, its easier to just jump to conclusions.

mark21742

oh, ok. Sorry....assumed

No, after fully torquing tty bolts I would not reuse them

you guys "think" you know things but i'll bet not ONE of you know the proper way to remove these TTY bolts.............bunch of SHEEP you all are...BAAA BAAA

mark21742

Enlighten me.....I know when I went change the leaking head gasket on her 200,000 mile Escort three head bolts broke when I was taking them out....what a PITA....so I'm all ears

What about checking ptv would you use your old gaskets?

mark21742

yes you could....if you have 0 deck height or your pistons sit down in the hole a hair you can measure with no gasket, then add your gasket crush measurement to get total PTV clearance.....

No gasket you get say .060" clearance.
You want to run a .040" gasket.
Add .060" to .040" and you get your clearance at .100"

But most stock ls1 motors have the pistons sticking up out of the about .005", so in that case you would need to run a gasket to check.

Just a funny quick story. I helped a friend do a head swap after blowing a head gasket on a 250 shot. Well I got to removing the headbolts and I noticed he used gold grade a standard style bolts!! It ran believe it or not for a long time till he blew it. He was low into the tens btw.

I can't wait to hear this one!

Let me take a shot:

1) Preheat bolt to 435* in oven for 37minutes
2) Spray rubber Bedliner on them
3) Fill bolt holes with 1oz water to ensure head bolt seals
4) torque with 1" (yes 1") impact gun until gun "torque's to yield"
5) jbweld bolt in place. We don't want those bitches backing out!
6) drink a millwaukee beast. Cause only real men know how the f to TTY a head bolt.

Am I close?
