Replacing knock sensor

[captain1]

Could someone give me a detailed description on replacing the knock sensor? I'm not quite sure how to remove it! Thanks!

HEAT, and lots of it!

Sorry to say they basicly require an oxy aceteline torch, heat up the pipe around the sensor and let it cool down.

They basicly rust weld themselves in there.

I don't recomend that you try this unless you know what your doing with a torch, and a propane torch won't make a difference.
