as the title says, a little insight. I just read the ls6 pcv conversion on ls1 how to.com and looks good, one thing they install the old pcv valve in line from the valley cover to the intake. Not that it is wrong, but isnt the baffle in the valley cover resrticted to act like a valve?? i have a ls2 set up i am building with the ls2 cover and i was told all i need is the hose from the valley cover to the intake. Are the ls6 covers different, (of course the knock sensor holes) but other than that. I guess i just want to know so i know what to do with mine. Any info will be appriciated.

 

I don't think there is any type of one way valve in the baffle of the LS6 valley pan. I still have the PCV in line as well. I got the newer style PCV - no moving parts just a smaller hole out the back.

called the stealership, for a gto with the ls2 they dont show any pcv valve. just the hose from the valley cover to the intake. there must me something in that baffle.

 

The LS2 valley cover has the pcv & baffle built onto it on the bottom side.. You want the ls2 valley cover part#12570471 along with u hose # 12594779.

that is what i got, ls2 cover and hose, I assume the ls6 cover doesnt have a built in type pcv system.

 

I have never seen an LS6 built in.

 

04' ls6 was the only year they did the pcv on the valley cover & carried the design over to the ls2/ls7... Use the ls2 cover it's a better design vs the old 00-02 ls6 cover.. You will not need a pcv as it's already built into the plastic baffle under your ls2 valley cover.

 

thank you guys that is the info i was looking for.

 

will this LS2 vally cover fit on a 01 LS1 block or will the last year (04) of the LS6 fit?

 

what is the part # on the LS6 valley cover?
