View Full Version : Noise from PCV valve hose

09-18-2007, 01:52 PM

I have a 97 grand am with a 3.1 V6. The car has been running great, then all of a sudden it is making a whistling noise. I checked it out and the hose that runs into the pcv valve collapses at idle and makes a noise. So the easy thing was to replace the $2.99 pcv valve. Well it still did it, so my question is, what else could it be?? Once I hit the throttle a bit the noise goes away and the hose expands. And it is really only the soft 90 degree bend hose that collapses. Any ideas?? Otherwise it runs good, the idle could be a little smoother, but not bad.

Ummm... Hose should not expand or contract at all. check for leaks or plugs.
