Default PCV System?

Hey guys,

When I bought my car, It came with the PCV system disabled. The hoses that connect to the throttle body are disconnected, the TB is plugged, and the hoses are still connected to the valve covers and the PCV itself still sits in the other valve.

My question is, is there any benefit from this system being disconnected? I have a crankcase breather which I was told is there because the PCV is disconnected. The breather spits oil around sometimes and when I beat on the car I get an oily smell, so I'm wondering if I should pull that out and just put a factory cap on the oil stem, and just connect the pcv system back up.

Any help is much appreciated, thanks!

You can see the breather and the PCV lines pushed out of the way^

You need to install some sort of pcv system...I would anyway. Here is a good read, with suggestions on what to do. https://ls1tech.com/forums/generatio...v-systems.html

You want the clean air to kind of, flush out the crankcase, while removing all the bad air.

What is a catch can? What do you guys suggest I do? There's a lot of work done to the car, so Idk if this was left this way for a reason. Here's a better pic:

Usually people do leave it like that for a reason...they break one of the plastic lines while working on the car, or something along those lines. These engines get a lot of oil in the intake. A catch can "catches" that oil, keeping it from going back into the engine. A good catch can, like the one in the link I posted, has an integrated pcv in it. The stock pcv system sucks at best. The can that 405hp posted is also a very nice option as well.

Basically the catch can allows you to re-route the stock pcv system in a way that functions properly.

Hmm i see. How difficult is it to install a catch can? I'm just not sure if I should leave it as is and deal with it, put it back to stock, or now, install a catch can.. But then again I don't like the idea of something else in my engine bay either lol.

But before I continue, is there any performance related advantage in having it setup the way my car is right now? Or do you just think someone broke something? I don't want to change it and have it result in my car running crappy or something

Also, could the PCV system be in this state because of the LS6 intake that was swapped in?
Thanks guys
