I just replaced my PCV valve along with the hose that connects to it since it was full of gunk. I couldnt find out what exactly its called since when I looked up pcv hose it came up with the plastic piece the other end connects to (which really isnt a hose so Im not sure why it'd be called that) went to napa and they had a heater hose formed the same way as the one I needed (it was listed as a bypass heater hose) but when I looked in Alldata in class it said specifically not to use a heater hose for the pcv hose (no pics for this either, so Im guessing theyre talking about the actual hose not the other thing) Looked under the hood for a hose shaped similar to that heater hose, and the only one was the one I needed. So, what exactly would come up if I left the heater hose in place? I had to replace that hose and of course I went to the junkyard as soon as I rememebered I needed it within like 10 min of them closing and (except PAP) none of them are open sunday. Dont want to use the old hose, cleaning it is hopeless and I dont want to undo the extensive cleaning I did on the car anyway.

 

Also I was told it was hard due to the fact it's an emissions hose, but Im not entirely sure it should be as hard as it is, the ends where it was connected to something was softer than the rest of it.

The risk is that the hose collapses when the engine pulls a vacuum through it.

 

The heater hose can handle only positive pressure, not suction. Replace the hose as soon as possible, but don't have sleepness nights over it.

That's what I thought initally but the hose I replaced it with has a metal coil within the hose so it doesnt collapse, and both ends are clamped down to the point where you cant even move it around, much less pull it off. So with the given details, what are the chances of it actually collapsing on me?

 

I did go to the junkyards today, and every legacy I found that had the hose was either cracked or in worse shape than the one I took off so replacing it is out of the question for the time being (mostly due to the fact I really dont wanna pay that much for a hose from the subaru dealership)

 

On a slightly off topic note, why are the tb gaskets so damn hard to find here?? everyone (and I mean EVERYONE) has to either special order it or get one shipped from the east coast.

Okay, it wont collapse. Only risk left is that it might not be able to handle the oil and gas fumes. Leave it in, and check it for cracks along the way.

There's no such thing as a stupid question.

I was always told that the only stupid question is the one you don't ask.

my teacher says the same thing, and is always proven wrong within 5 minutes

So you're on the shoulder of a road with the hood up, the back open, and someone stops and asks "Are you having problems?"

 

Here's your sign...

Here's a better stupid question... when you're searching frantically for something you've misplaced, someone comes up with the very helpful "Where did you see it last?" Get my gun...
