The codes are labeled permanent and they return immediately. Just had it out tonight driving around. The idle still sucks when not up to temp and there is a substantial knock somewhere...
In other news, I did change the pvc (A few days before this recent scan). What caused this pile of sand type substance under the diaphragm and the lifter springs? Looks pretty gnarly lol. It didnt fix anything either. I still always have a lot of vacuum under the oil cap.
If anyone wants to replace this pcv-ccv without removing the valve cover, just cut a small notch on the outer band with wire cutters or something. Then run a screwdriver around the outer edge with hammer to break off. It was an easy 15 minute job.
