What's this hose?

Was changing front oxygen sensor on my 98 OBW, and noticed this hose. Comes off the top of engine block (don't know what the specific part it's attached to is), and just hangs there. The pic is from the passenger side. Is it supposed to be like that?

If someone doesnt chime in, trace it back to its source and take a pic, then I can tell you. Otherwise wait till the sun comes up and I'll look on mine.

is that the vacuum line that attaches to the bottom, about the middle, of the air intake half way between the filter box and the throttle body. you know, the one that slips off when you check your air filter and it makes it so the car will not idle, wants to die, until you reattach it.

 

the other end goes to ..... anyone.

One goes to thecrankcase one comes from the valve covers.

 

Im guessing that he isnt stalling its from the valve covers.

Thanks, will definitely take some pics tomorrow.

Looks like the passenger side head breather. It is probably disconnected in the back, where it attaches to the big black box.

So here's a pic of where it's coming out of:

Now where do I connect the other end?:grin:

There is one of those from both sides of the engine. They should connect to a T then connect to the snorkus (air intake box/hose)

 

It will be under the box on the pass side, if i recall correctly.

Hi nipper,

 

Would that be the one labeled "blow-by hose" on the pic below? Should it connect to the box that I marked with red arrows?

 

Thanks.
