Well I am putting the head back onto my motor right now and I am following the Honda factory manual to a T.

I get to the head install part and it says to torque the head bolts to 22ft-lbs. Is this correct? On all the other honda motors I have done, B/D/H series it is a lot more than that.

Can someone please verify this number??? Someone with experience???

Thanks in advance, Phil.

 

Not sure what the actual spec is, but aren't you supposed to turn it 90 degrees 3 times after you get it to the initial torque spec, or something like that?

 

These are stretch bolts. You first install them to 22 Ft lbs, and if they are new, 90 degrees turns, in the pattern three times. Old bolts, only twice.

If you don't follow that, you will have issue. Follow it and you are golden.

The end results is up there. I used a 24" 1/2 breaker bar to do it, and I wanted to move up to the 36" 3/4 bar on the last round.

 

I am resuing the bolts.

So is this is: Torque initially to 22ft-lbs. do 90 degress on each bolt twice in the specified sequence?

So even if the torque wrench clicks at 22 (which it does) keep going until they are rotated 90 degrees. Then do it once more?

Thanks guys, please verify what I have said here.

 

Yes.

So following the pattern in the manual, do the following:

1. Torque all bolts to 22 FT-Lbs
2. Turn each bolt 90 degrees
3. Turn each bolt another 90 degrees

I personally use a breaker bar and a Snap-on TA360. I would not use a Torque wrench as it may damage the internals and it is not required.

 

sounds good, that is what I will do. I figured 22ft-lbs was not enough.



Also any idea as to where I can get stock injectors from? It's the last thing on my list before the engine goes in to be started. Someone has to have them laying around from after boosting, no one answers my WTB thread.


Thanks a million!

 

DO NOT use the torque wrench to continue tighten the bolts. Use a long breaker bar. once tightened to 22 ft-lbs, put a white paint mark at 12 oclock on each bolt.

Then 1/4 turn in sequence.

Then another 1/4 in sequence, till the paint mark is at 6 oclock. Foolproof

 

Missed that part.

Good call

 

Don't forget this part. If you don't do it in the proper sequence, I believe you risk warping the head.

 

gotcha everyone. Took care of it tonight and was extra careful in following the procedure. Thanks!
