I picked up a new Delco PCV valve today and wanted to buy replacement o-rings, but they're only available as part of a kit from the dealer. I'd rather not spend $18 when all I need is the o-rings.

Does anyone know what size o-rings are used on the PCV valve and housing?

95 Series II

Thanks,

I'm unsure of ths size but you may be able to go to a autoparts store get the o-ring for next to nothing.

PCV o-ring size that my 96 L36 uses.

Small o-ring that goes around the PCV valve is a – 116 or ¾ I.D. x 15/16 O.D. x 3/32 Thick

Large o-ring that is orange from GM is a – 218 or 1 ¼ I.D. x 1 ½ 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.
