Yep. Is it messed up or something?

Yeah its got a little hole underneath and need to replace. That hose goes behind the motor. It makes my car idle weird and exhaust makes popping noises.
I put tape to cover it and seem to work for now but need to replace.

That piece that has the hole is removeable. It disconnects from the PCV valve right there and from the intake. Mine just got a hole in it too. I just took some normal vacuum line and hooked between the PCV valve and the intake and used a couple hose clamps and I have not had a problem yet. You don't have to replace that entire PCV hose that goes back behind the intake and over to the driver side valve cover.

Do you have pics of the breather set-up? I haven't heard of that before.

I went to the dealer trying to get that same piece. They said that you have to buy the hose/PCV assembly. Mine had tore apart like yours. I'm pretty sure it was around 80 dollars. I ended up making my own out of stuff from Autozone.

dude same thing happend to mine they called it and engine breather... went to dealer and bought the $80 hose assembly but found out that I only need the little rubber hose tip that had the hole in it... so took the little part with the hole to autozone and they gave me a good replica of the little part that had a hole......So pull out that little rubber hose its only like 2"inches or less and take it to autozone and you will get a good replacement... FYI I took that $80 part back and got my money

Thats what happened to mine. When it idled it sounded like it had a cam in it (back when it was stock)

I just put tape over it and its been fine ever since.

lol, same here(sounds like it have a cam). I also have tape over it at the moment. But does not look good at all.
Thanks for the link, I am buying the catch can. But looking at those threads I notice they all have the LS6 intakes and none with Ls1 intakes. idk

I went to autozone and bought a vacuum plug/cap kit for a few dollars, removed it and capped off both sides. Took about 3 minutes. It's worked fine on all of my LS1's!

Are you saying you have no crankcase ventilation at all? That's not good. You should at least have a breather on there.
