Plastic Vacuum tubes from IAC and from Crank vent

[Blueberryyum02]

I notice yesterday that I was hearing a whistles sound coming from the engine, so I started checking lines to see and I noticed that these to tubes have small cracks in them not sure if it's leaking as when sprayed with brake cleaner there was no change in engine idle. But as I twisted the tubes to make sure the was sealing the whistle sound stop when I got the crank case vent hose twisted in a different angle. Do the dealer still carry these tubes cause I'm looking to replace them. As I'm leaning towards the O riches might be going bad, or can I just replace the O rings.

Yes, as of the last time I checked (a few months ago). I believe that some of them come only as combination assemblies, like the brake booster hose with check valve.

Ok thanks Joegr, it was racking my brain trying to figure out the whistle sound it started out as a hiss but when I did the coolant parts this past weekend it turned into a whistle so I just started twisting line and moving them. When I got to the pcv line it took some time but once it sealed up the whistle stopped and I notice that the hp is much better throttle response when on the gas is very much noticeable. It's funny how a small leak can effect a engine so much. I think once a replace this a/c commpressor it'll really come alive since the clutch is dragging when it's off or on.
