Timing Chain replacement

[Greasy_Holly]

Hey yall,
I am going to be replacing the timing chain assembly on my 1981 Buick Regal, 3.8L V6. I was wondering if anyone has the torque specs for all the hardware for bolting the sprockets back on. I'm just trying to rebuild what I can in order to get it driving properly. Also was wondering if anyone knows where I could get new hardware. Im ordering the assembly from RockAuto but they dont include new hardware.

You don't need new hardware unless you break what you have.

For a SBC it's 20 ft lbs. I can't imagine it's different from that to be honest.

Make sure you clean out the threads so there's no oil residue. And use Blue thread locker on the hardware.

Look up Buick V6 torque specs on google. It varies from make to make. If I used the 20 ft/lbs spec on the Olds 350 I did, the cam gear might be resting against the crank, Olds spec is 60 ft/lbs.
