You get the LS6 valley on? If you end up getting the turbo setup, let me know, I have done alot of research on pulling vaccum on the crankcase. With a turbo and the setup you would damn sure be able to cancel out the PCV for sure.
Cody, i got the Walbro stuffed down in to the tank.. all is good.

What you mean about canceling out the PCV?
You just goin to run Breathers on all of it?
When i figure all that out, im puttin my STS kit on.

Are you going with bigger valves on your 317's? What turbo are you going with? I am definetly interested in the PCV info that you have. Do you need an LS6 valley cover if you have big vents on both valve covers tied to an evac kit?

Yep LS6 PCV system is on and the motor is still burning oil. I bought a new set of valve seals that came in today, I'll try to put them on this weekend. If that doesn't fix it I don't know what else to try.

I did buy Mark's turbo kit I'm interested in the research you have done....send me a PM or a link or something?

Going to block off all the stock stuff, I have an LS6 valley cover, run to an AMW catch can, then a line to the intake of the turbo so the turbo will pull vacuum on the catch can which will pull vacuumn on the crank case which will help the rings seal better.

Thunder- you have the brown seals on the exhaust and black on the intake right? I have heard of people using all intake stem seals and burning oil before.

1slow- My dad had an AMW catch can plumbed between the LS6 valley cover and intake manifold (N/A engine) and still ended up with oil in the manifold. The way these engines drink oil seems to be almost as fatal as not having enough head bolts.

Yes Im going with what Richard puts in them which is bigger, Im looking at a pt-88 with coated exhaust housing and blanket or an S80 ot S85, havent decided yet for sure. Im going to run the gt-67 I have for a while and recover from some of the other costs of getting this SOB running then Ill upgrade. The new S-series turbos are VERY nice and make some crazy power for their size.

TSP uses blue seals all the way around, I can't remember the name but I think it started with a V.

We will see but it seems to be working well for the guys on tech, with the vacuum from a turbo.

When you talk about vacuum from the turbo, are you talking about pulling vacuum from between the turbo and the throttle body?

tap into the filter basically, the turbo is pulling air through the filter so if you tap a hose in there it will try and pull air through there which will be coming from the crankcase through the catch can which takes the oil out of the air but still pulls vacuum on the crank case.
