I was replacing my water pump and accidentally broke this hose and I'm not sure what it is. It looks like a run into the crankshaft area but I'm not sure what it's supposed to connect to. I hope these pictures are good enough to interpret the ones that are the close-ups with numbers that i can't read is of the piece that separated from the end still in the engine compartment.
Luckily i have these pics because i cant find the piece.

Okay, it could be the hose for the PCV valve or the hose for the emission canister at the back of the car.

I do not have a vacuum diagram but look around for the other part of the hose.

The second third and forth pictures are of the other end. Actually i found a better picture of the hose before i went ahead and took off the other half. This should help.
I'm unable to put my hand there with the engine running and the other lines connected but i can definitely hear hissing and the idle level jumps up and down.
I also get a thud like sound which i have heard before i change the idle control valve months ago.

I'm looking at this picture which i took this morning, i noticed the hose with the white fitting was disconnected so i assumed it attached to the metal tube below the throttle body because it had nothing connected to it.
Comparing the pics i see the broken off piece is supposed to attach to the hose with the white connector on the end.

The first picture looks correct. The second picture looks like a water line and the hose is not the hose you have in the picture.

Yes, yes the first picture is from when it first happened the second picture is after I had taken the broken piece off and was reassembling and notice that that metal piece did not have any connection to it. so I assumed that the white coupling piece went there but it doesn't.

I just found this online and it looks like both lines from under the throttle body connects to the one hose with the white collector on the end of it.
