Sorry, not good news.
Taking the oil filler cap off a good motor, and just letting it rest on the filler tube while gently holding it, will cause it to jiggle... only. The "puffs" will be equally positive and negative, and cancel out any outward flow that would lift the cap. With the good motor it feels almost like it is slightly sucking it down... but not.
And there will definitely NOT be any smoke from a good motor's oil filler tube.
