I think i need a new PCV hose that connects to the right side of the intake manifold. I'm hearing a strange humming noise comming from that area...so I think I have a leak. Can someone help...i looked on shoebox but i'm confused as to which i need to get.

1993-1997 RH TB to valve cover hose for PCV air intake 10128365
1993-1997 Plastic elbow for PCV hose in RH valve cover 12550625
1993-1997 RH Valve cover grommet for PCV hose 10088126
1993-1997 PCV grommet in intake manifold 10240678

Is it one of these?

Its this part: http://shbox.com/1/pcv_pipe.jpg the black hose on the right side.

Thanks.

 

Yes thats the hose.
You might be able to use fuel line to replace it.

 

lol i know the one in the pic is the hose...but what the part num is it?

it's one of these 4 i think?

1993-1997 RH TB to valve cover hose for PCV air intake 10128365
1993-1997 Plastic elbow for PCV hose in RH valve cover 12550625
1993-1997 RH Valve cover grommet for PCV hose 10088126
1993-1997 PCV grommet in intake manifold 10240678

 

Nope none of those.
Try the fuel line to replace it will only cost you under a buck.
It should work.
The only thing in the list for the PCV valve is the grommet 10240678.

 

Ok, unless I missed it, I don't know what year the car is, or engine size. To keep from having to put this in all the time, edit your signature and put in it the year, engine size, if it's an auto put a4( if it's a 4 speed, if it's a stick put m5 for 5 speed, m6 for 6 speed. Being as though u have listed 93-97 year make parts, but not knowing if 95 and up is like 94, especially after adopting obd1.5 and obd2, but if your car is like mine the pcf valve has a hose or line that's about 3-4 inches long and u shaped, attaches to the pcv from another vacuum port @ the same level about an inch and a half closer to the firewall, like he said use fuel line, I can tell u from experience that getting vac lines for our cars isn't as easy as going to the nearest chevy dealer anymore, many vac lines simply aren't made or sold by gm anymore, least that's what I'm finding out, like a molded brake booster vac line? Chevy says nope don't make em any more, and a straight piece of hose looks stupid to me, but it functions. If u have any better luck with getting vac lines for the booster, and the little black plastic lines(the parts store stuff is really not durable and u have to really watch for kinks) please let me know.

 

93-94 use the U-shaped hose - its the lowest hose in this photo:

95-97 run a metal tube (different shape for different years) from the PCV valve to the port on the front of the intake manfold, under the throttle body, with rubber connections on both ends:

ahh sorry it's a 97. I figured by showing the photo they would all be the same......So i should use fuel line then... Hmm, so can I basically go to the auto store and just say I need some fuel line or is there a size I need?

 

Probably a 3/8" diameter hose, but since you have a 97, it will be a 90° elbow at the PCV valve and you won't be able to use a straight piece.

GM PART # 12556257 for the pipe and rubber elbow at the PCV valve end (that elbow is not sold by itself).
GM PART # 12551389 if you also need rubber elbow at the front of the intake.

 

ugh!!! so is my best bet to head to a dealership?

 

You mignt be able to find something that would substitute at an auto parts store, but both parts are less than $20 (even at retail) at the dealer.
