Default PCV wire needed?

There is a wire that has been reffered to as the heat sink wire that attaches from the pcv valve to a stud on the head. I didnt put it back on after working on my car. What the heck is it for? WHo has left it off?

I think its useless.

I believe It's a heat sink wire to trasfer heat from the head to the PCV valve to help keep the oil vapors vaporized(to be burned easier and move through the intake better) but I dont really Know for sure. I would like to know for sure myself.

Not a good thing to live by...I think if it wasn't needed, the engineers would save the dough it costs to produce (though next to nothing).

Ha...Well, let us know if you end up with any negative effects in the future. Though I can't seem to figure out its importance either, I'm going to have to side with the engineers on this one...

I've been running without it for 2 years, no apparent side effects of NOT using it. I also use an AMW catch can.

Ahh...this is good news...
Perhaps I'll try it then. I've been running a Greddy puke can for a good while. If it does in fact only somehow keep the oil vaporized, it certainly wouldn't be needed with a catch can.

I took it off awhile ago to test my new catch can(which didnt work), so now there is no catch can and no wire thing, no problems.

I can't imagine the oil would need to be kept heated going through the pcv valve.

My guess is that it's an electrical ground. Remember static electricity is caused by moving materials through a pipe/tube and such. We have that kind of stuff everywhere here at work. It's real important when you're dealing with flammable ****.

No, it's to keep the PCV valve heated, otherwise they wouldnt have used such a fatty wire.
