Oil dipstick keeps popping out
 

i see the when i check my oil the dip stick is out, just resting on the rubber part. Dont know why crankcase pressure is blowing it out, bad pcv? any ideas?

prob bad pcv but could be other more serious problems. check the pcv fist it is esy and simpe to do.

Not to scare you but on piston cars i know thats a sign meaning your engines about to blow (head gasket or related parts). It means you have excessive blowby gas.

On a turbo car, proper functioning of the PCV system is even more important than in a NA car, due to the positive pressure in the intake during boost. A bad check valve, for instance, can cause crankcase pressurization, and blow out seals, not just the dipstick.

I have had 1st-hand experience with this problem on my wife's 1.8T Passat.
