Relax, this isn't another "what kind of PCV should I use" thread

Here's my situation. On the back of my GSR sits the stock PCV black box. One hose runs to a small vacuum port on the back of the block, the other which contains the actual PCV valve normally hooks up to a vacuum source on the manifold. I went ahead and pluged the hose into the block as normal, but whenver I plug the actual PCV line into the intake manifold, the car reacts like is now has a massive vacuum leak. The idle rises quickly and proceeds to bounce over and over and over non stop untill I plug that line comming off the manifold and the idle will drop to normal, rock steady. Like I said though, this only happens when I connect the PCV to the intake mani, if I just plug that port on the intake mani and leave the PCV hose open to the atmosphere, no problems.

Any idea what could be happening? I guess there's no problem leaving the line as it is now except that the PCV isn't being asisted by manifold vacuum durning non-boost driving, but obviously that's not how it's supposed to work, any help would be apprieciated.

 

bump for the early crew..

 

I got that same problem, bump

 

The idea is to vent the crankcase directly from the block fittings and eliminate the PCV valve.
I capped the fitting off directly at the intake manifold, removed the black box, plugged the hole that was underneath and plugged the brass fitting directly above it.

I then vent the crank case straight from the 2 freeze plugs on the back of the block to a catch tank with a return line (endyn setup) I have had absolutely no problems with this setup and it eliminates blowby

Heres a crappy pic, if you need a better one let me know

 

Yea, looks like I'm just gonna say screw it and go the catchcan route already.
