Snap-On Techangle Torque Wrench / Heads
Just got my heads back from the machine shop, and I'm thinking forward to what I'll need to start putting the engine back together. On the list is a Snap-On Techangle torque wrench, but I'm debating sizes...the 1/2" will obviously do the job, but the 3/8" will be far more useful in general. I'm wondering if anyone has measured the torque values on the 1st and 2nd 90-degree turns of the head bolts (MY 87), and if its w/in range of the 100 ft lbs max of the 3/8" Techangle or if I'll just need to go with the 1/2" model.
Thanks.
Thanks.

I got the 1/2" model. You will want this for the heads. Trust me.

Get both, problem solved.
The 1/2 inch one is going to be pretty hard to use on the head bolts, unless you are a big fellow, a real big fellow.
I have the 3/4 one for the head bolts.

Come on Greg, I used the 1/2" and I'm not that big. 6' 200#. I can't imagine using a 3/8" though.

From page 15-116e
1st stage 20 Nm (15 ft. lb.)
2nd stage 90* torque angle
3rd stage 90* torque angle
From page 15-117
1st step 20 NM
2nd step 90* of rotation
3rd step 90* of rotation
4th step 90* of rotation
From page 15-118
1st stage 20 NM (15 ftlb)
2nd stage 90* of turn
3rd stage 90* of turn
Which of these is correct?
And, if 1 = 15 ft lb, 2 = 90*, 3 = 90*, a torque wrench should not be required for 2 & 3, correct?

This has recently been discussed. The third 90 is the issue.

I think the first one is for the engines with studs, and it has been discussed if that was not a miss print or not.
Correct in that you do not have to have a torque wrench for the angle part, but that is one of the things that makes the Snap-On Tech-Angle wrenches so useful is it not only gives you torque readings but also degrees.

You could use a breaker bar and a angle measurer thing you put on the wrench that has a little arm to hold it in place. But why not have a really cool torque wrench to make it perfect. I was able to get within 1 degree with my Techangle. Figured that was close enough. I don't know if you could get within 5 or 10 degrees with one of the add on things. I had very learned people who have built many engines advise me to not use one of the add on angle thingys.

about $500 for the 1/2" depends on your rep.

I'd be willing to lend you mine if you promise to return it unbroken. I don't get there often, about once every couple years. My business partner lives there.
