Tighten spark plugs?

Just remember that anti-seize will get everywhere if you aren't careful. A little here equals a little everywhere.

 

Hand tighten

1/2 turn

Done

 

idk about 1/2 turn most of them when i used the ratchet after inly could turn 1/8 and it felt tight

 

let the car run for 10 min and didnt hear or see any problem.

also when was hand tighting the plugs i could feel and tell the gasket being crushed when i was using a extension and the spark plug socket. than used ratchet after.

 

the "rule of thumb" in the shop is, 2 fingers on the 3/8 ratchet as tight as you can get it. index and middle finger

 

yes that what i did

 

it the same feeling like how when you close a ketchup bottle or a shampoo bottle has that extra lip when it closes?

 

always done it by feel.

you can feel when the crush washer is fully crushed pretty damn easy. A plug on the looser side is better than going to tight n striping the head.

 

This. With some anti-seize on the threads, it's very easy to feel when the plug has bottomed when you hand tighten.

The torque value given in the FSM is for dry threads. If using anti-seize, reduce the torque by half, per: http://densoiridium.com/installationguide.php

 

It's pretty cheap insurance though. I'd rather use it and not need it.

Cold engine, and a little anti-seize on the threads!

 

imo i never use anti seize on spark plugs

 

pretty sure NGK specifically states NOT to use antisieze on their plugs.

 

why is that?

 

why would you ever need it...

 

^Anti-seize is advisable when you are threading something into aluminum.

Yes, because they are catering instructions for the least common denominator. You can do damage if you apply anti-seize then torque to FSM spec intended for dry threads.

 

afaik they have a coating on them to prevent it as is. and if you put antisieze on them 1. you over torque them, 2. can cause more issues with metal actually corroding together.

but i dont remember where i heard this from so take it with a grain of salt.

Nope. Did mine in my 2007 F-150. Didn't break one and I'm not mechanically inclined.

 

Start them without a rachet and do this
