Just in the process of a lot of work on the Golf, 1 thing to tick off was the DV, my mates just removed it, there's a tiny drop of oil in the rubber section, however it's completely intact and actually looks in good nick! Where it plugs in has oil aswell, is this a sign the PCV needs replaced? Or is the DV faulty?
Either way it's being replaced, just want to know if it's worth to keep as a spare?
