Retensioning Headbolts After Head Gasket Change

[1208]

I just changed my head gasket in my s13.

I know a guy who had a rb25 and didn't Retension his headbolts and had all sorts of trouble.

I was just wondering if anyone knew if you had to do this for sr's

the thing that would make it hard how when your tensioning the head bolts the last two tensions are in degrees, not foot lbs or anything

you need a half inch degrees gauge adaptor, the head bolts and washers need to be lubed

[doo doo]

Assuming you have all the right method up to the degree bit, the final torque for is 108-127 Nm (80-93 ft lb). This is on a GtiR R but assuming it's the same (torque to 59N-m, then 108-118 N-m, back them all off completely, 36-42N-m followed by final turn of 90-95 degrees). Use light engine oil for lube rather than moly lube (I've heard moly lube is effective enough to require a reduction of 10% in torque for stock head bolts)

I've already got the head on and tensioned it up to spec. I've done 100 or so kms since Ive changed it. Do you have to retension the headbolts or is it fine if you tension them right when reinstalling the head?

[Dorifta]

You tension the head bolts once, just like any other bolt. If u have already done it then the jobs complete

yeah i have to agree. i've never heard of anyone pulling the top of the motor back off to tighten the head bolts again.

Thanks for that.
