ok when torquing the 15 head bolts, the manual says step 1) torque M11 head bolts #1-10 in sequence to 22 ft/lbs.... then step 2) is to add 90 degree twist to M11 bolts #1-10 in sequence. my questions is after i do step #1 can i go over all M11 bolts #1-10 with the torque wrench at 22 ft/lbs and double check they are all at 22 ft/lbs before moving on to step #2 or will this **** up my torque readings and the following steps?????

im using stock GM TTY head bolts on an aluminum LS6 block

 

wouldnt be a bad idea to do so, as long as your at 22ft.lbs not like your torquing anymore..i dont see a problem with double checking

 

that was my thought process as well

 

You will not get an accurate result but it likely won't hurt. The reason I say this is because once you tighten to the first value, the torque wrench will click with the bolt rotating so the friction will be dynamic friction that is being read, which is typically lower than static friction. When you re-tighten the second time, you have to overcome the static friction in order to get the bolt to move and this value will be higher than the original torque value. Not sure I explained it very well. The initial torque is only to provide seating to the joint.

 

I always go around the entire set (in the given pattern) at least 5x's. Not so obvious on high-torque stuff like heads and mains, but you'll see a very evident amount of give on some of the low-torque things like covers, oil pans, etc. Mainly because of gasket crush. It's too easy to do...

 

cool thanks for the answers guys

 

Vettenuts is right. You're over-thinking this IMO.

 

newb alert.....not familiar with the angle torque process, can someone explain?

 

That's really tough info to find:

smart ***

 

well not really, unless yu live under rocks this TTY thing has bean around a long time. Maybe you should read more tech articles on the net than ****?

 

If you invest as much time reading as you spend selecting smilies, you might not embarrass yourself so much.

 

I say go over them a sec time but don't over tighten them . The older torque only engines for instance when tq-ing the head bolts if You went through them a sec time You always had 1 or 2 usually the first 1's in the order that would need a little more to even them up with the latter 1's .

 

that's is exactly what i found out for myself

also im using new stock TTY head bolts, anyone have any idea why they have sealant pre applied to the threads. I just dont understand why they would put sealant on a bolt that goes into a blind hole

 

i usually go 22 44 68 on the torque never had any problems

 

That's Locktite thread-locker .

 

at first thats what i thought/assumed but its very thick like an RVT of sorts.
