Stock PCV's don't necessarily hold boost well. Many leak at over 7 lbs or so. APS is constantly developing products for the Z
Just thought I would share this with you all:

 

So where do I get one?

 

Interesting. I wonder how much APS wants for one of them...

Do they have any data or proof of the stock valve actually causing problems?

 

Should be free for APS owners.

 

+1 on the price.

I assume this would work for any kind of FI?

 

They tested numerous valves and most were prone to leaking around 8 lbs and beyond -

Hook up an air line to yours and test the pressue it begins to leak at

 

where? when? how much???

 

 

Most; all but TN...........










yes, it will work with all applications

 

bahahaha, only if installed at an authorized APS dealer

 

nothing is free in this world - especially not now days

 

So, is it avaliable or not? and where can i get it?

 

I'd be interested in seeing how much leakage they encountered at boost levels past 8psi. If, for instance, we're talking .01psi leakage at 9psi then I woudn't bother. I'm just wondering if this is really an issue or something along the lines of the shielded CAS.

 

cool little product there.

i pressure tested mine last year and it didnt leak, but i cant remember what pressure i tested it to. this is a good thing for everyone to have tho, since its cheap insurance... you wouldnt want to trust that little plastic POS stock one for very long.

keeping pressure out of your crankcase will improve ring sealing, reduce oil consumption, and improved crankcase vacuum can make a little power too.

 

Or u can just grab a one way valve of any honda out there for nothing. junkyard technology, tested to 40psi+.

 

your right, there are 100 other options as well.

the best thing to do would be to actually reroute that entire PCV setup, since it vents to the manifold it will not get vacuum when you want it the most, under boost. It should be ran to a vacuumed catchcan if you want the most complete setup, but thats a lot of plumbing for something that isnt currently presenting an issue.

 

interesting

 

vent to atmo. Problem solved.

 

I want one. Come on, tell us where to get them.

 

that is what I did. put a breather on the valve cover (picked it up at Advance auto parts) and stuck a nipple cover on the manifold.
