Tomorrow  I will  install the Heads on the 2.2L

 

           Could someone give me their explanation of what they are doing to torque the heads?(all I got is the Hayes book... It's pretty much a headache to use the book)

                        

            What is the acceptable method in the forum for torquing the heads on  ....  torque sequence (and loosen then tightening process)

 

   Thanks, Micky

torque all in sequence from center to outers, all to 27, then all to 37, then all to 47 ft/lbs.

 

loosen all bolts 180 degrees, basically til loose, no torque

 

tighten center bolts to 24 ft/lbs

 

tighten outers to 19 ft/lbs

 

tighten all in sequence from center to outers, first 90 degrees.  

 

Then again around an additional 90 degrees.

Thanks! Gloyale.

 

     on the part,       [[[    loosen all bolts 180 degrees, basically til loose, no torque    ]]]

 

 

                       Start with center bolts? (loosening)   180 degrees/ (half turn counter clockwise) (bolts will actually be loose on just a half of a turn?)

                                       { This half turn CC will yield a no torque bolt ]

 

                 Got the idea on the rest of it......

 

 

Thanks, Micky

loosen in revers order.  Outers first, then centers.

 

and yes 180 loosened should yeild basically no torque.  at least lesd than the 24/19 ft/lbs you will be going up to before the final 90+90 degree tightening.

Well, she is running.
got about 25 miles on her.

Seems to be running well..
Was stalling out a couple times...... strange@#$???
May have been a vacuum leak.. found a rubber
cap/plug all cracked,,, replaced it... it was a
1/8" vacuum tap on the intake manifold sorta near pcv valve.
downstream about two inches towards passengerside head...
I don't know why the taping is there, wondering if anyone
might know?

Also, I could not remember where the battery ground
wire bolts to? Where should it be bolted to?
I bolted it through intake manifold bolt (one closest to firewall)
I just was drawing a blank.. on that one.

Thanks, Micky

Good work getting that done in the field!

 

The battery ground goes to a small bracket at the starter, where it bolts to the bellhousing. 

 

Intake manifold bolt would be a poor choice, as it does not torque down very tight, so the manifold is free to float just a little on the heads with expansion.

Thanks!
Yeah, it certainly was a nervewracking experience.


I will look tomorrow..at the Outback
. I think my Loyale's (have three Loyales but, only one
is still amongst the living others-" yard planters")
Had theirs mounted in that fashion....

If the outback doesn't have that bracket, I will have to swipe it from
one of the "yard planters"...... and that would be cool! When cars share
their parts... then their spirits get to live on!


thanks Micky
