what check valve in pcv system? I have been reading through some of the post on the pcv system on a boosted ls1. I keep seeing about using a check valve on it. What kind are you using, and where are you getting them from? I can't seem to find anything.
If you have a GM dealer close, you can go there and ask for the valves used in the brake booster recall on the 08? GMC Acadia's, Buick Enclaves, Chevy Traverse, etc. They are nice little black one way valves with nipples.
GN check valve here! Im going to use a GN type check valve in mine when my catch cans come in this weekend. I use to run one in my 87GN some years back. There a bit pricy, but definatly are very well made as others im sure .Just my prefrence is all.Heres a picture of it if intrested,,, that i found early today

Im just trying to figuire where the best place to locate mine would be ? Should i place it right after or before the PVC valve before it goes to my catch can? OR should i place it right before the LS6 valley pan nipple?

trying to revive a good thread and to get some clearity
Does this look correct? The PCV valve I have there will be replaced with the one way brake booster check valve mentioned above. I found one real cheap.

The PCV valve should stay because it regulates how much air actually gets through. I just got my GM check valve 20861501 in the mail and it looks like it will work well. 3/8 barbed ends, not too big. It also limits the flow about as much as the factory PCV valve so you could perhaps use it as the PCV valve too.
