Ok i read over the LS1 service manual and it says to torque them to 15 lbs and then go over them again and give them an 80* turn, well here is the problem, i can't find a torque angle gauge/ meter/ WHATEVER THE F*&K it's called and no one knows what i am talking abuot (of course)

does some one know of a torque value for this or do i have to go down to the local chevy dealership and see how much they are goin to charge me to use theirs?

 

Matco sells an angle torque meter that should do what you need, and they do mail order:

With a torque-to-yield bolt you won't get good results without one of these, good investment to make.

 

cool beans!!! i think this will be in my tool box jsut cause i will come in handy...

 

I saw one in an Autozone a couple of weeks ago.

In the meantime, 80 degrees is "almost" 90 degrees if you want to just eyeball it....

 

I dunno about you, but guesstimating on the reciprocating assembly gives me the creeps. Pull one of those spindly-looking TTY bolts beyond its plastic range and the game's over.

I agree, John. If you take a pencil and draw a mark on the top of the bolt and another mark about 80* later, then all you have to do is make the marks line up. You can even use your old highschool protractor to make sure the marks are accurate

I find this method much cheaper

 

FYI the main bolts on a LS1 are TTA (Torque TO Angle) not TTY (Torque to Yield)

BTW what is the "beyond its plastic range"???

 

I think he's talking about the range that the bolt is designed to stretch to hold the torque.

 

plastic range is the designed stretch point i believe, too far past the design and snap.

I don't think I'd trust my motor to a protractor and marks on the bolt and head somewhere. Too much guess work and not enough accuracy. But hey, that's just me. You'll get a much more accurate spec with one of the tool listed.

For all the money and time invested in one of these motors is 40 bucks for the proper tool really that big of a deal?
