I hope the link works:


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..,.
the ride is a 91, L98, A4 with 68k on the clock.

Thought??

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.
