Is there supposed to be a strong vacuum at the oil dipstick (97 GS auto)

I noticed a hissing noise on my 97 GS auto 2.0L (non-turbo). I found that it was coming from the oil dipstick tube because the dipstick was not all the way seated. I got to wondering, is there supposed to the such a strong vacuum there?
