changing sparks...



  PB 172 phase 2
I changed the spark plugs yesterday, torqued them to 25 Nm(first time using torque wrench and it clicked every time) Question is - how do I tell if it was done correctly?. I drove it after and the initial idle sorted itself self out a lot quicker, almost instantly. Don't think I can hear any backfire but then with the whirring going on(rear bearing), it might be hard to tell at this stage.

Nip them up and put the leads on in the correct order and thats it, you cant really go wrong, make sure you use the correct plugs tho.

If it starts and doesn't blow them out you're probably fine.
25nm is tiny anyway, so you would be doing well to undertighten them.

You are fine, 25Nm is a proper torque for plugs. I always handtighten them without overpowering, so they cant break. If you overtorque, they will break and you will be in trouble.
