No, not a lot of initial timing. Probably the most misunderstood subject on this & other forums. The factory HAS to be conservative with timing because it does not know the end use of the vehicle. I think you are getting excessive blow by [ puff of smoke ] & this pressure is foprcing oil into the PCV.
From what I can tell, no significant blowby.

PCV removed, there is just a light steady whisp of vapor from the breather. No chooching, no real pressure.
