Catch can in APS PCV set-up
Catch can in APS PCV set-up I'm sure some of you APS f-body guys have added a catch can in with the APS PCV setup, if so, how did you add it in there? Did you get vacuum from one of the turbos, vent it, where did you T it i, etc? I've been hearing it would be a good idea to do, just not sure on where to T it in and what options would be best. Thanks!

Anyone? I've been reading of a few people having problems with the APS PCV set-up, anyone make any changes that have helped?

i would imagine it would be like any other setup.
pull from the valve covers to a catch can
depending on what catch can you get...
u can pull from a T from the turbos
vent it thru air filter
or both

Well, for what it's worth, my tuner kinda reset mine back to a more factory set-up, and included a catch can. He did that so that the baffles would be in place for pcv in the valve cover, and because the APS set-up was having MAJOR lean-idle problems(like, the car wouldn't idle, just die). I'm currently just using the supplied check valve, but my over all set-up is the same as it is in the pictures on my myspace page. Just look at the APS PCV pics. Snazzy, huh?
Keep in mind that I'm the one complaining about burning oil or lean idle. You know, I never did use a stock PCV valve without the check valve. That just might work beautifully, but I need to find a way to plumb it in, since I don't have any of my stock PCV equipment anymore.

hmm, my last set up i had a fully vented setup, blocked off intake/TB/1 port on pass VC, and i ran one port for each VC to a catch can w/ breather and had breather on oil fill so it was totally vented. I am trying to get my car to be much more streetable and would like to not have it fully vented anymore so i dont have to change oil every time i drive it, haha (exaggerated). I know the APS has a set up for you but i'd heard it hasn't been working too well, maybe i'll just do my own thing from MM's write up

i had 1 port on each valve to a catch can (non vented) to the turbo inlet side
small breathers on the other ports on the valve covers
ls6 valley port to 1 way check valve to intake manifold
big air breather on oil cap
barely any oil in the catch can after 2 years of not even checking..only reason it was check now cause i am getting a vented catch can and removing the oil cap breather.

What is the difference of putting breathers on the remaining VC ports vs simply blocking them?
I now has an ls6 valley cover so i have this new port as well, what does it help adding it back in to the intake with a one-way vs. just blocking it?
Thanks, i appreciate the help. BTW, with the way yours in setup, do you still have to change your oil much more regularly? Thanks!

back up. Last year i ran a vented set up. Everything capped, then both VC's ran into a catch can with breather and breather on oil fill. Should i just stick with this set up for my new APS system or should i switch it up to a different style. One main question here.... Should i stick with my vented catch can or go to a sealed style? Thanks!

My current vented catch can was built to fit in my AC accumulator spot but i'm putting the AC back in so i'm looking to get a different catch can to fit somewhere else a bit easier but i don't know if i should go with a vented style or sealed. RevXtreme has a nice sealed set up if that will work, if vented is best, i'll stuff my current can somewhere!

Update: No more oil burning issues. Works just fine with a stock PCV valve. Had to do some rigging, but that because I threw all my PCV stuff away prematurely.
In any case. I'm happy with mine, but I suppose it could be designed better for WOT operation. It's closed, with the breather hose (from just behind the filter) going to the fresh air connection on the pass side cylinder head. The vac line pulls from the PCV connection on the driver's side to a catch can mounted on the front of the pass side cyl head. This way it pulls air through the crankcase from one side to the other and sweeps it fairly well. Then it just goes thru a stock PCV valve to the vacuum fitting on the intake manifold.
I was pulling a bit too much oil into the CC with APS's check valve, but with the stock PCV that's not a problem anymore. Oil burning issues were a combination of my own stupidity (not checking catch can when PCV is pulling buttloads of air through it) and APS's PCV design not functioning well on my motor for some reason.
If you want pictures, I can post a link.
Hope this helps some,
