Broken pcv breather valve
So do I just curl up in a ball and die because I broke this?
I capped off the intake side but I am pretty sure this won't help lol. I can't just put a breather filter on the braided end... what do? This sucks lol

Yeah its the 1way valve on the intake tube. I did manage to find that hose on rockauto. looks totally different but I guess it works. Waiting for it now

To be able to drive without issues plug both ends, the line going into the head is the fresh air inlet post MAF so it will run like a vacuum leak. I wouldn't drive the car unless you have to with the fresh air plugged until you get the replacement part, you could likely get away with removing the entire line and replacing with a vacuum line without the check valve just don't get into high boost.

I don't think Rock Auto has the pcv part you are looking for? Well if you can't find a stock replacement, here is one may work for you. It is listed for other cars. But work the same.

Use a thick wall rubber hose (emission/fuel etc.) connect to your intake with hose clamps/pinch clamps and the other end to your braided hose? If you can find a pcv with same OD that you can insert into the braided end like the stock one.

Temporary fix until I get the kappa pcv hose.

New pcv hose does not work for HHRs. I guess my custom one will have to do

Here it is. Arrow points to Valve cover

That seems the opposite of what it should be. Air should flow from the valve cover to the intake.
Sounds like GM set it up to pull fresh air in here and then the I/M connection pulls the air out of the crankcase. Weird setup.
There are two check valves: one is in the IM and the other is at the fresh air inlet. The one in the IM makes sure that there is no pressure into the crankcase during boost; the inlet valve makes sure that flow is only going from intake to crankcase. I'd check the inlet valve before ripping apart the IM.

I know the LNF pcv is bonkers but this is 100% factory stock car and that's how mine was installed. I think this hose is the inlet part of pcv and the outlet is elsewhere.

Outlet is into the intake manifold.
Normally, I'd say GM knows better than us... but the fact that they screwed up the LSJ system so bad makes me believe otherwise.
LNF's don't seem to have nearly as many PCV related problems when compared with LSJ's though. Pulling in fresh air might be them trying to mitigate some of the downsides of direct injection though.
