Why is the PCV valve grounded?

I would say it's just there to hold the valve in place and absorb some of the vibration, think of it like a Barry mount for avionics on aircraft
while you're there, notice the injector grounding strap on the aft RHS fuel rail mount, that is a ground strap

You are correct. It was mounted wth the large gauge wire for heat transfer purposes only. They wanted to insure that during temperature changes of the outpside air, the valve would continue to operate as designed.

That is an interesting observation. I have a 99 LS1 but have done the LS6 valley cover mod. I still have my PCV valve strapped. Wonder if I should 'unstrap' it... Guess I could do so and see.

I don't think it really makes a differece, my new engine will have the LS6 style PCV but I'm going to leave the strap on there.

I put the PCV in my 1998 C5 that has a small hole in it and NO VALVE. It is for cars that use a lot of oil, it is suppose to keep excess oil out of your intake manifold. I know it is not "an official" fix for the C5 LS1, but it is for many V8's in GM Trucks.

Have you checked to see if it works?
