1.6D Stud for Stud

[VWrabbit317]

1.6D, later one with the 12mm triple square head bolts. close to being up and running. I have the turbo on and I sourced a TD injection pump Ill be installing in the next week. I can get ARP head studs for a pretty good price and I was thinking about just putting them on and not having to worry about my stock ones. My question is, would I be fine doing stud for stud? In torque sequence, remove the first bolt, install stud and torque, remove second bolt, install stud and toque and so on. Bad idea or would I be fine? Recent compression test showed 510-515 on all cylinders so I really didn't want to mess with the pulling the head off if I don't need to. I appreciate everyone's opinions, thoughts, and experiences!

Interesting question.  With all the others tight to the right torque you want to go in sequence and take one out and put one in. 

So what will happen in between?  You are not going to put pressure to the part so I would go for it.

You might try to do a compression test on the final result before you hit the key to start it.  Pull all injectors out and test without compression build in the cylinder until you are testing it. 

My question is about re-torque sequence.  Are you just going to set them at initial and then pull to a final and be done with it? 

Anyone else see a problem with this idea.  I don't

This is fine.  I do this all the time.

Re torque after 2-3 days of driving and then 30 days.

Doing it today to my 1.8t, as the stock hg has started to weep after 250,xxx

What a turd !   Hopefully a bit more clamping force with seal it up.  Hopefully...

Good to hear. Thanks for the replies guys.
As for the torquing sequence.. Should I install one stud and torque to book spec AND THEN go back and torque all studs to arp spec (125ft) OR should I install stud and torque straight to the arp spec on each one as I install it?

I would install one stud, torque it to spec, loosen it 1/4 turn, torque to spec, loosen it a 1/4 turn and torque to spec, then move on to the 2nd and so on. If they are new studs that process will do all it can to relieve the residual stress in the studs*if they are brand new never been ran*. You probably won't have to retorque if you do it this way, but you should try.

would it be normal to have a small amount of seepage out of the back of the head gasket while doing this?

No.
There is no oil pressure there,.. just gravity pulling oil from the block.
