Funny this post is here, i just emailed the Edelbrock tech support a couple of days ago concerning this exact same qeustion! I asked him why i find a small amount of oil pooled up everytime i pull the plenum cover off my performer intake. His reply was "That is normal to have a little oil in the intake that happens with the factory intakes" I don't know if i realy trust this, but thats what tech support says..
