Im going to be pulling the head some time soon (i think its a bhg).
I got my hands on some brand new head bolts from the dealership and had some questions about the installation procedure in the FSM.
There are 4 steps and a "phase" in the process.
Im I am not mistaken the first four steps are:
- tighten 72 ft.lbs.
- loosen to 0 ft. lbs.
- tighten to 26-32 ft. lbs.
- 75 degrees clockwise
Here is where I am confused...
"phase 5" says 75 degrees clockwise again?
Can someone help please?

o ok...
so i do tighten the bolts down a second 75 degrees for that "phase 5" or whatever. thanks for the heads up and the tips. definitely got to go grab an angle wrench.
does anyone know why they dont just call it "step 5" and call it a "phase 5"?

Also, try to get your hands on an angle wrench. Eyeballing is unacceptable. If you can't find an angle wrench, get a protractor and measure the angle of the socket sitting firmly in the bolt head. Two people isn't a must, but it's a great idea.
My mechanic buddy that did the work got stumped on this part. I ended up cutting a hole in a paper plate to slide over the socket extension. I was able to use a protractor and make the appropriate markings for him. It worked well, and the head was fine until the motor spun a bearing 1K miles later.
I'd suggest a blackstone labs oil analysis to determine the health of the motor first. This would have saved me from doing the HG, and just replace the whole motor, which I ended up doing anyway.

you can eyeball it or use the torque angle gauge.. either or works. I used the angle gauge to be safe.

Eyeballing might work fine, but why risk it when you can hit walmart for a $1 protractor?

You should definatley NOT tell this to all the freakin idiots driving cars these days. Good mechanics would know what the hell to do and about where to stop, other people......
definatley bad.... bad bad idea..... lol.

just to have this stated for people that might happen upon this topic.
1. if you have some time, DONT REUSE THE HEADBOLTS.
2. if you have to have it done, when you get the bolts tqed down, check there torque and if its much above 100 like 120 130 140 etc.
DONT REUSE THE HEADBOLTS
