Did it raise and lower with rpm?

Hi,
The pitch stayed constant but it would sometimes completely disappear at lower RPM.
I appreciate your thoughts and time on this. I know how hard it is to troubleshoot a problem from a written description. I may try to go out and video it if it pops up the next time I start the car.
I was even wondering if it might be the Air Oil Separator, given the smoke that poured out with no idiot lights coming on.
Thanks for your thoughts.
