how tight are you guys torquing your head?? and im talking about arp studs, im going to be re-torquing my head and would like to here some opinions. currently im runing ls/vtec and i torqued it down to 80 foot pounds

 

I use Golden Eagle head studs, and I follow their instructions. Final torque being 72 ft. lbs.

I believe ARP recommends 63 ft. lbs with their lube and 80 ft. lbs with 30wt. oil.

Following their instructions ensures you don't torque a stud/nut past it's yield point. I ran over 30lbs of boost on OEM headgasket with no copper spray/orings/ect. and had no issues with manufacturer's recommendations.

 

Yep. I went to 65 Lbs with mt ARP's with the moly lube

 

80 ft lbs with 30 wt here

 

i usually do 70ft lbs w/moly on all motor cars and smaller turbo cars and the big turbo cars i go to 80ft lbs w/moly using arp or golden eagle studs.

 

i do between 75 and 80 ftlbs as my final tq with arp's. oil on the bottom of the stud, moly on the top. i also follow the helms specs and sequence for the first 2, then just go from that one to 75 as a 3rd step

 

great input guys!!! thanks for the confirmations ill retorque it maybe that takes care of the stupid oil leak in the corner of the head were i put the plug for the vtec!!!

 

100 lbs

 

what about the bottom end the arp mains, crank and rods just see every body doing and im building back my b18c5 turbo with 85mm wesco piston and crower rods stock main bearings and what oil pump should i use, i heard they upgrade the pump

 

if you did not get it plugged good its not gona help.

 

71 ft/lbs

 

<----Fail!!! I did 80ft lb with moly lube on the ARP's

 

as per ARPs instructions i do 3 steps to 85 with moly lube

 

I do them in steps of 10lbs, 8-9 steps final at 80-85ft lbs all in a oem sequence. With moly lube..

I don't like reusing head studs because of this, but it doesn't lift.

We have tried 65-70lbs with moly lube. Anything over 14psi or so it was like a fountain of anti freeze out the puke tank.

 

Yay, I'm not failing then cause that's what i do

 

I torqued using haynes sequence in three increments of around 26ftlbs
And a final torque of around 80ftlbs with moly lube on both sides of the stud
for my lsvtec,As for rod bolts torque to 26ftlbs. Loosen. Torque to 26ftlbs. Loosen.
And do a final torque to 26ftlbs.

 

well that would be a fail because arp says 65ftlbs with moly and 85 with conventional oil. Its also better to torque with conventional oil rather than moly, you get a more acurate torque reading.

I torque mine in four stages up to 90 lbs never had a problem with straight 30 weight oil

 

stock gsr took head off need to know how much to torque it

 

The directions with ARP studs I just bought for a gsr block say 80 ft/lbs with moly lube. I did 82 and I'm going to go another few degrees before I put the cams and fire it up.

 

any one know where to get the stock specs for a gsr

 

how/why is motor oil more accurate?

 

ive been told by many engine builders that motor oil is more accurate, ive always had good luck with straigth oil and bad luck with the moly lube so thats what i stick too

 

does this mean that @ 70lbs the head lifts?

will it do it @ 80lbs?

 

i always use arp moly lube or anti-seze. + torque in 2 steps up to 70 ft/lbs. so far i havent had any headgasket problems. (car makes around 850 hp.) i do think the blocks we choose to run have alot to do with that.

 

true dave, very true LOL
