Dipstick is fairly sloppy. The new pcv and gromet do not seem like a super tight seal. Both are not factory. It is easy to pull the pcv from the vc. The yota dealer can get both these and im sure a dipstick as well.

Now that i think of it on my old malibu when i pulled the pcv oil would push thru the dipstick.

Ive been wanting to go the dealer anyways and mess with the salesmen. Sounds like i got an excuse now.
