Default grounded pcv?

i just finished the install of my elite engineering catch can on an '02. very nice product, ungodly simple installation.
what i've never seen mentioned though is what appears to be a ground wire from the pcv body to the head. does the air movement through the plastic line cause enough static charge that it has to be discharged from the metal pcv body to the block? or is a 'just in case' kind of thing? also, how do you keep from unscrewing the can every day to see if you caught anything?

Must be an LS1 thing ... no "ground wire" on the PVC system on the Z06s (LS6).

Are you suffering from catch can collection inspection OCD?

my wife said she'll support me either way, just don't show it to her.

It might be a support, also I wish EE would include a 90 dergree elbow to come off the PCV...

you know, i didn't think of that. it is awfully heavy wire for just for a ground.
and yeah an elbow might work nice. it isn't really that bad if the hose is routed toward the front and down to get to the can though.

It's definitely not a support. I have it too and it's too elaborate to be a support. It looks like a ground wire or some sort of conductive contact. GM went to the trouble of making sure the wire touches the metal body of the PCV underneath the rubber sheathing. Now, all that remains is to figure out why?

I tried going forward with the hose but it came to close to the belt/tensioner... at least in my case.

I have no idea what the wire is doing coming off the PCV if it's not structural... Unless the TB has to be isolated from the engine block to eliminate any electrical intereference from the ignition. I like that one! That's my story and I'm sticking to it!

Ok, its not a ground thing at all. It is however, a wire or heat-sink that conducts heat to the PCV valve from the engine, to assist it in heating up to the engine temperature. This will help insure that it doesn't get stuck with any muck inside of it and insure the proper operation overall.

ok, as a heat sink that would keep the oil vapor from cooling and leaving oil to get stuck in the pcv.
as a support it's a heavy enough gauge bent in a 180* loop which could support the fragile plastic line, keeping it in line with the port on the intake.
this leads to it being a multifunctional well thought out accessory component.

i came off of the pcv, front and down under the intake hose laying across the front of the block, back up behind the intake hose and port to the top port on the can. it lays in there very nicely.

tb is sandwiched between a plastic air intake and a plastic intake manifold with rubber hoses hooked to it. i would assume all the electrical connections are grounded themselves. but you can stick to it if you want to.

Oil vapor is conductive... Yeah! That's it.

Leave an old man to his fantasies will ya?

dgrant3830 is correct in that it is there to warm up the pcv to aid in keeping resisting clogging. However, the way the rubber wraps around the mount there is actually a very small potential vacuum leak. I'd recommend installing a normal pcv with barbs and connecting with tubing to prevent that if you are running any sort modifications and a tune. It's cheap and easy enough to replace.

Remember, the hotter the blowby gasses, the more likely a good percentage of them will squirm past the relatively thick wire bundle inside the catch can. This is why simply locating the can away from the main heat source - your engine, will ensure that condensation of tiny oil droplets will occur inside the "can".

Getting past the PCV valve is a good thing; getting past your catch can is a bad thing.
