think I found my vacc. leak. I never resealed the IAC to the adaptor.... sealed the adaptor to the TB but not the IAC... Waiting a lil while for the sealant to make up and then I'll start it again

and I found my power steering leak.... YT is dropping a new hard line in the mail for me. Once I get that I can tighten everything down, install the new software, hit the track, and then hit the dyno again.

well... my issues are not ironed out either. I re-sealed the IAC but with no real luck. It will idle nice w/ a good AFR for about 3 seconds then the idle drops down and it'll run super lean (off the map). I am going to replace the IAC when I get back to philly and hope for the best.... These are the same issues I was having with the idle before the motor build so don't go thinking thats the issue

Do you think it could be the auxiliary air unit? I just had to replace an IAC in my WRX. They are expensive.

i am going to replace it hopefully tomorrow... I will let everyone know

Tom:

How much torque are you using for the main bolts? I have some documentation that says 20 ft-lbs and other documentation that says 29-35 ft-lbs.

Thanks

the main bolts are a sequence. 11ft-lbs to start then a sequence of tightening them by angles. You should pick up an angle bit for your torque wrench. Thiswill help you precisely measure you stretch torque angles.

ya you need to follow that factory torque sequence......

I've noticed when caging bearings that the main oil clearances don't even come out right if you don't use the factory torque sequence.

TomsSVX · #**448** 10-15-2007, 09:05 PM

same reason my oil clearnances on the rods were all wrong with overtorqueing them too.

I see. 20 ft-lbs is for the other case bolts not the bearing bolts. The bearing bolts go 11 ft-lbs then 90 degrees more. The manual shows the sequence too.

Thanks

no... I think you are seeing 20* as 20ft lbs
