Since my motor isn't back in yet, I was thinking about changing over to the ls6 pcv system.

my car has the old 1999 pcv set-up. I will be using a LS6 intake.

what all is needed?
any sites with pics?
Part #'s?
cost to change completely over?
worth doing?

thanks Felton.

isn't there some grinding required to install the valley cover?

Yes, there is a piece to remove. I'm not having luck recalling the website with a description. Try this: http://www.users.bigpond.net.au/acer...me1Source1.htm

does the piece that needs removed have to make contact with the valley cover? or just take it down far enough for the cover to lay flat?

If you look at Viper's link, the fifth picture down, that shows the underside of the LS6 valley cover, its the tube that runs on the bottom side of it that runs right where you need to grind down.

so both pcv inlets get plugged on the valvecovers.
then the hose goes from the corner of the new valley cover to throttlebody???? any pics of the ls6 set up on a vette?

highgmc

ordering the ls6 pcv parts tomorrow
thanks! <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />

I got the valley cover installed.
where does the pvc hose coming out of the valley cover connect to? to the tb? plug both valve covers?

or does the pass. side valvecover vent still goto the tb?

I didn't need these parts. I reused my PCV valve, and used a foot of 3/8" hose. I didn't need the plug for the valve cover either, I just used a rubber cap.

I got away with only spending $47 for the whole conversion.

last of the Z28's

are you saying if your car came with the ls6 intake(2001-2002 fbod)you dont have the pcv oil consumption problem i read about with so many f-bods?

Run a hose from one valve cover to the other and you're set.

The only part you really need to order is the valley cover itself. GM parts direct sells it for $37.18...I can reuse my pcv valve, and just buy a 90 degree connector from Pep Boys for a couple bucks...$45 tops for the job.

Actually, the line comes out of the valley cover into the pcv valve then into the manifold, not into the TB. The tube from the valve cover goes to the TB for fresh air. But I capped that off and I'm running a breather cap where my oil filler cap used to be. This way fresh air goes through that instead.

the new ls6 valley cover outlet connects to the pcv valve and hose that then connects to the manifold. ( I didn't notice anywhere to connect the pvc hose to the manifold)

the drivers side rocker cover gets plugged.
?right?

02BlackWS6

Yep, the driver side gets plugged. On our stock LS1 setup the pcv valve connects to a little rubber piece then to the manifold behind the TB. Well you leave the pcv valve in its stock location except the other end of the pcv valve connects to the LS6 valley cover instead of the passenger side valve cover. Hope that helps. It should cut down on pulling oil in the intake manifold...Basically the engine is being vauumed down from the valley cover instead of the valve cover..But the hose going to the TB to the valve cover provides the fresh air into the crankcase like an LS1 setup.
