Default spark plugs question

I have a question for the specialist or expert tech/mechanic.

I've just replaced the spark plugs yesterday & torqued the plugs to 14 ft-lb (manual calls for 15). Anti-seize was applied to the threads. Afterwards, I read in the service manual that if the thread has oil or lubricant, only 1/3 of the torque spec should be used. Now, I am thinking, anti-seize is not oil, but it seems to provide some lubrication.

Question: should I pull out the airbox, washer reservoir again & ease those plugs back out a bit? Or, am I ok as is?

Thanks for your feedback,
-Henry

Anything is possible that they are either too tight, loose or just right. Being a HD diesel mechanic I will say if you torqued them at 14 lbs you should have nothing to worry about. It's not like because you used antiseize you torqued them to an artificial 42 lbs.

Also, any good mechanic or do it yourselfer should after experience have a good enough feel when bolts,nuts and screws are properly tightened.

If the plug crush ring has seated, you should be fine.

Uh, yeah it is. The antiseeze cuts friction, so you end up turning them farther to reach the torque than if you had clean, dry threads.

Yes, the crush ring has seated. I am more worried about over torquing.
