When you buy a new PCV, you DON'T get a new o-ring on any of them that I found. However, if you go to the Dorman HELP! section (red packages of parts hanging up), you can by an o-ring assortment that has at least one that works. Otherwise, your auto parts store may have loose o-rings you can buy. All it has to do is slide comfortably on the PCV valve from the bottom. I bought a packaged assortment of rings to get one for about $2.99.

Well that sucks, I have an o-ring set so it shouldn't be a problem, Although I still don't know what size they are if they are not present when I take a look.

So what I understand is that there are 2 o-rings one small one that is at the bottom of the PCV and a larger one that seals around the PCV body?

Thanks

Jeff

PCV o-ring size that my 96 L36 uses.

Small o-ring that goes around the PCV valve is a 116 or I.D. x 15/16 O.D. x 3/32 Thick

Large o-ring that is orange from GM is a 218 or 1 I.D. x 1 O.D. x 1/8 Thick.

The AC Delco or GM PCV valve replacement kit makes things easy.
Part # 89017274 comes with valve, o-rings, and new improved style plastic top.

my bonne squels/whines too. Just wanted to make sure if it was the same kind of squel that everyone else was experiencing with the absence of the 0-ring.
here'* vid. Sorry for the sound...but couldn't really get around the engine noise. If you listen closely you'll hear the squel present throughout.

Can't open the file, but if it is squealing while driving then probably not this seems to only happen at a low idle, once the rpms start to come up the squeal goes away on this car and from what I have read in the posts I copied shortcuts to earlier in this thread. This squeal sounds like a belt or a bad bearing.

i forgot to warn that it is a quicktime file....
squel/whine is present at idle {sometimes}...and also whie driving...but only up to a certain gear....which i'm thinking is 4th/OD...not sure though.
So going by what you said i guess my problem is totally different....

Have you tried removing the belt and driving a short distance to determine if this is the problem?

Have you removed the Oil filler cap to see if it goes away?

Have you shifted into 3rd to see if it goes away?

Is it under load or when you are cruising?

It does go away...{or dies down?} Somewhere around 3rd or 4th. I'll have to count the actual gear next time i'm out.

Happens both times...while under load in the lower gears {1, 2} and also when cruising at those lower speeds that involve the lower gears. It does it at idle too.

The car has been doing it since i've had it {over a year} and i haven't really had any problems. I'm just trying to determine where and what the sound is coming from so I can get rid of it. its just annoying at this point lol.

Remove the belt and try it. Just remember that you will not have PS, ALT or your Water pump while trying this.

No need to count gears just hold it and shift manually.

Judging by your description I would say no that the problem is probably elswhere.
