Default No, you need an open flame or spark to ignite it.

A hot pipe will just cause it to evaporate off. Might stink for a little bit, but that's it.

Default About a minute or so.

Whipe down the area so your socket doesnt strip the 02 sensor and has good grip on it. Didnt know there were directions for this but this stuff works great.

Default Pick up a 24" 3/8 breaker bar from Sears and it should pop right out. Can't get enough torque with

that little wrench.

Default Longer than that. Give it 15 minutes for something that's really jammed.

Tap the part occassionally.

Cool, will do. I'm just afraid that I'm going to snap the wrench with a breaker bar. Oh well!

Default It's a very thin oil...it works it's way in.

It's not magic though...it takes time. Just soak it, and tap it occasionally to break the surface tension on the fluid and help it along as it finds it's way into crevices. I've left things soaking overnight if I know in advance it's going to be a problem.
