After driving it and warming smoke stars coming from dipstick tube when idle as you can see in the video.
Running smooth, temp normal just had it serviced with mobile1 oil, new filter..,.

Whaleman is correct. You PCV valve is defective and not allowing internal gases to escape "normally" so it backs up and comes out your dip stick.

Checked the PCV valve and it’s connections all seems ok and working properly..!!

I’ve noticed also some oil on the tube neck .. could be spitting from the dipstick tube.
