2000 Saab 9-3 repair Question 6 cyl Front Wheel Drive Manual 106K miles

I have a tiny oil drip. When I crawl under the car I see a drop from the oil drain plug. I recently had the oil changed and checked to make sure the plug was tight. It was. I took it back to the shop and the guy said the drip is coming from the PCV Valve directly above the oil plug and needs to be replaced. My question: Does this make sense? Can I easily replace the valve myself. If I can find it?

Ok now, as per oil leak on your 9-3se, there r a few places u need to check, 1 oil pressure switch located behide starter motor above oil drain plug area, 2 check if oil is coming from your intake right from the throttle body where black intake tube is fitted, if wet with oil replace o-ring seal, that seal will cause a major looking oil leak, maining oil coming out anywhere it can, 3 check if oil is coming down from the side of the engine where drive belt is located if wet with oil when looking from top RH side then u may have a headgasket not sealing, what use to do the trick was re-torquing the head bolts, not really sure if that still works, all we do now is replace head gasket, the only way that oil would be coming from your pvc valve or [oil trap ]used for crankcase ventilation, is if that oil trap box is blocked, if so there is a new updated version to address crankcase ventilation, so before anything check these areas for leaks, if my info helped post back, others want to know, info may help someone else.

Just to answer your question if u can perform repairs, yes just disconnect battery neg terminal first, because u will be using tools near to the alternator wiring coming from battery, tools needed a 13mm socket & short extension plus racket handle, a long type screw driver to pry vent hoses off oil trap, if u go for the updated kit which I recommend u will need a 1/4" drive 10mm short or long socket or if u r good a 10 mm short wrench use to remove oil filler tube, refitting is the reverse of removal process, only thing is new kit comes with new type hoses that run in a different position from the old ones, if u decide to do it post back for this routing info.
