The U shaped hose that is at the end of the PVC tube looks very brittle on my GrandAm. Also I've noticed that when my car is turned on the hose goes flat. Is this normal or should I replace the part? I noticed this when I tuned up my car the other day.

Got a pic of what you're talking about? The only u shaped rubber hose that I can remember is for the evap system. All the pcv stuff is plastic iirc. Its been a while though

It's dark outside and I'm in my truck atm. Well I think this is a picture of it. (It's the U shaped hose at the end)

Im certain he is talking about this part.

However I dont know what the part number is, I replaced mine with a generic one at advanced auto but it was too soft and the vac kept collapsing it and causing a whistling noise.

I'll just go ahead and replace it. What effects would it have on the car anyways? Mine collapses every time my car runs and it looks brittle.

It shouldn't collapse period. Get one off a car from junkyard or dealer for this. Or rock auto. Acdelco only I would want. Check for a rattle... shake the end of the pcv and if it rattles it's in working order. If not you need a new one.

I'm going to replace it Thursday. What effects would it have on the car though? Worse gas milage, more emissions? Anything noticeable?

The U shaped piece at the other end of that connects to the evap solenoid. One side goes to the PCV valve, other goes to the evap solenoid, both connect to the top of the UIM behind the TB as a vacuum source.

It definitely shouldn't collapse. If it does, then you wouldn't be getting flow through the evap system when the solenoid activates to purge the system. If it's cracked or loose, it could cause a vacuum leak. I'd replace it. If you can't find just that rubber piece, you can replace the whole pipe, or you might be able to replace the rubber piece with a piece of silicone vacuum tubing.

Cool, that's what I was looking for. I'm going to replace the whole tube assembly
