How do I run vacuum lines turbo motor new style ls6 valley cover?
I have been looking and haven't found any answer for a boosted motor.
I understand the routing on non-turbo, which is, line from TB to pass cover, valley to intake, plug everything else.
with a turbo motor and no pcv or oneway valve (just fixed orfice), the boost pressure will pressurize the oil pan to "X" psi.

I think he is asking how he would use the valley cover. I have the same question. If you serch on here and look at people's PCV setups, they NEVER include a LS6 valley cover. Its always a catch can system routed to valve covers, but never includes the LS6 valley cover. Im in for the info as well.

i have found info on the old style ls6 valley cover, but that uses an external inline pcv valve and the new style has a fixed orifice tube which doesn't require a pcv valve anywhere.

I just left the one tube in the front of the ls6 valley open to the atmosphere. Did the same for the tubes on the valve covers. My oil filler cap is now a large breather and there is a small breather on the rear driver side valve cover. Blocked off the tb tube also. I've been turbo for 3 years now and no issue

I just spent all this money and want to know how someone has successfully ran a fixed orifice tube valley cover on a turbo motor. If I am the first to attempt this let me know and I'll post up what I try.

can you show me one example that uses the new style ls6 valley cover with the fixed orifice tube not the old style which requires an external pvc valve? I couldn't find it for some reason.

run your valve covers to a catch can, catch can to the inlet of the intake. Take the ls6 valley cover and tap into the inlet of the turbo/super. The reason its ok to go straight to the inlet of the turbo is you will never see boost there only vacuum and the whole point of a ls6 valley is to be a oil scubber. Its basically like a oil catch can of itself. So bring that puppy straight into intake(maybe tap the end of you filter etc) then your set. Or just EFF it and cap it if you want but you can never have to much ventilation!!

plug everything on your valve covers, get rid of the factory pcv crap. Just get 2 -10an bungs weld one on each valve cover. Run some 10an line off each bung and route it into a Jaz puke tank. I have this and just drilled out the other side for both lines

^^ not entirely....sometimes the more ways or areas you have to vent your crankcase is better. In fact in a lot of applications I have seen the engine needed more ventilation! Its not very hard to figure out where it goes....Treat it has a open crankcase source or treat it has a open "filtered" crankcase source. So many ideas you could do with it. Like I said before, since it is filtered already I just ran it to the inlet side of the turbo/supercharger... easy peezy. Cap it if you dont want to mess with it. Just make sure you have plenty of ventilation or you will be blowing dipsticks out etc...

I know this threads abit aged but never a bad time to bring up a good thread/
ive found a few pics on this that mgiht help but im wondering for rear mounts, would running a long as line to the intake side of the turbo for vaccum be too long?

Not a twin turbo, but a twin catch can none the less. id assume youd only have to run one line to a fresh air sourse, but id also image that you can t off the the vacuum line to both turbo inlets.
