Aircraft; Procedure
I understand the need to keep the airplanes moving; but until there is a true fix for these issues; It would have been much faster if the pack and or bleed was deferred right away; instead of just running the packs on the ground via APU to try and replicate. Since this potentially was from engine oil/engine bleeds; running the packs via the APU bleed; did not make sense. That doesn't eliminate the engine; engine bleed and oil as a suspected source of the fumes; since the engine was not running. That plus the remaining smell; is why I had to stand my ground to get more done; to agree the aircraft was safe to continue. I felt the chance of it reoccurring in this case was unacceptable.
A320 First Officer reported a fume event during preflight resulting in a maintenance delay.
