STS guys how's your PCV steup? I've read just about all the PCV threads and recently just read MIGHTYMOUSE's thread and was wondering what routing/seup were you STS guys running and is it effective?
I know a lot of people use a vacc. line from the inlet of the turbo to draw vacc. but that poses a small issue/more hose for rear mount guys.
I am currently running the STS pcv syst. and mainly just get the crankcase vapors upon decceleration and very little oil in the intake if any besides the normal amt. that almost all vehicles get.

i run a breather on the drivers valve cover, a breather on the passenger valve cover. i run the ls6 valve cover and run that line to a catch can and then to the intake. catches oil and relieves any pressure. i have had no issues since i went to this set up.
The factory STS PCV system sucks. If you hook it up according to "some" of the instructions you "may" have gotten, you will pressurize the crankcase. If you hook it up "right", it still isn't adequate. Breathers ARE adequate, but a vacuum pump may be even better.
EDIT-- When you get a decent tune (NOT Nelson) and up the boost, your centerforce clutch will be in serious need of replacement.

How are you guys routing your PCV systems? I have heard so many different ways using catch cans and check valves, the main purpose of this thread was trying to get actual field input from guys with modded PCV systems.
Car runs good off of the Nelson tune but still needs to be properly dyno tuned. Centerforce clutch is holding strong at 10-12 psi with no slip,chatter or any issues and has near 22K on it!

I run a vented catch can no issue at I get about a tea spoon every month or so.
I run both valve covers hoses to the can with a breather then on the on where the stock pcv port on the intake I use that for a cacume source to quell the oil smell works great and I built it at home.

Stock truck STS PVC here, But I have seen a few people run a moroso exhaust evac set-up with the venturii (sp) tube mounted after the turbo. Everyone claims it works good.

Have the stock PCV line running to an AMW catchcan and a breather AFTER the catchcan but BEFORE the PCV. Get a little vapor residue on the filter, but the can and intake stay dry. Before the breather, the catchcan would fill w/ oil in a matter of a day or so and pump a LOT of oil into the intake. The breather is the key to making it work 
A vented catchcan (like the Moroso one) would do the same thing.

Anyone know where I can get a 3 fitting catch can with a filter on top?
I think I am going to try the "OUTLAWZ RACING" set up, running both valve covers to a catch can and the PCV line from the intake to the catch can for vacc. and possibly have a small inline filter in the intake vacc. line.
Or I could T the valve cover lines together if I can't find what I looking for.
Thanks again for any input/info given but still open to more suggestions!
