LS6 pcv system
 

I'm switching my pcv system on my 347 iron block build to an LS6 style. I've already acquired the LS6 valley cover, my question is how do I go about plugging the existing pcv tubes in my valve covers, do I need to block both off? And do I use the GM# 12568011?

You need the hose in post 6 if you don't plan on using a catch can

Yea that cap will work for the rear passenger vacume port


You will use a rubber vacume cap for the driver side

Plug and hose ordered, thank you very much
