I'm about to replace my PCV valve real soon on my '92 SE. Heard a lot of people talking about replacing the O-Ring. The last time I checked, the rubber piece that is fitted inside the housing port that holds the PCV valve looks kind of like it'* pretty well set inside there (probably the original I'm sure).

How the hell can you remove that rubber piece if so where it doesn't break up and piece off? Also where do you get replacement 0-Rings since most auto parts stores wouldn't know what the hell you were talking about if you mentioned an O-Ring being used with a PCV valve on that 3.8 engine? Anyone know the part GM number, say, for a 1992 SE?

I think someone had to mess around to find the right size O-ring. I would go to the dealer and get one - probably charge you 50 cents but at least you know it'* the right one.

Yeah I just had to replace the lower o ring. Just get a kit of o rings. Costs couple bucks. The upper one is thicker... so I dunno, order the kit from gm direct.

ok, i hate intruding in on everyone'* posts, and bringing up my own car troubles, but oh well....
I never replaced any o-ring when i replaveced my PCV valve, should I be stopping down to the dealership and getting the o-ring?

Check the integrity of the existing o-ring. If it'* broken or crusty, then change it.

I just replaced my PCV valve, and I reused the o-ring because it looked fine. Seems to be ok.
