checking head studs on 3.2 ???
I'm in the middle of clutch replacement and am working on the
"While you're in there" stuff. Checking head studs is one of those things, I want to know if what I did is good enough. I put a wrench (socket) on each head stud and applied pressure maybe 25 ft lbs (just a guess). Is that a good check for the studs? And if not what should I do different? THANKS MUCH..................KC

For a check, that is entirely appropriate. Maybe even 30lbs is ok.
you will get varying opinions from loosen it first and retighten, to simply put a wrench on there and see if it is tight. My method is a) if it is broken, well that is a problem. b) if is leaking at the base, then something is wrong (like a stretched stud) c) if it is not broken, and my torque wrench clicks at 30 lbs, I am OK to let sleeping dogs lie.

I would not try 30 ft-lbs because non of the books by Wayne, Bentley or Anderson says anything like that.
Why would you torque 30 ft-lbs when the rebuild calls for 24 in 2 steps (Pre-torque and final wet) meaning: grease on the studs, washers and barrel nuts? Also, to guess this important torque by hand makes no sense. Get a calibrated 3/8 drive torque wrench, set it to 23-24 ft-lbs and check. Why not do it right?

Thanks for the input
, since I was checking for Broken studs rather than trying to re-torque the heads I believe what I have done will be suficient.I just wanted opinions from others to confirm. Another thought is.....why not get out my torque wrench and check it with the proper settings why didnt Ithink of that................ besides I have another week before all my clutch parts will be here.
