I was going to change my PCV valve on my 94 Civic 5-speed, but no-one
carries them. Is this a dealer-only part? It's only $15 retail per
majestic honda, so I might just drive down there and get it. However,
I was looking at it and I can't figure out how the grommet comes off
after you pull the vavle out. Should it stay in the engine or should I
replace it? Haynes doesn't say anything about it. Any info?? Thanks!!
