My best advice is for you not to touch your 401K. You will most likely not qualify for a loan as loans are provided only for certain situations (school, medical, foreclosure). A withdrawal would have to include a 10% penalty and Fed tax at 20%, so you would only net just over $700 out of the $1000 you are requesting. My advice to you is to seek alternative means to get this money (credit card advance, pay day loan, RAL on your tax refund ) as you most likely will not be able to touch your 401k for this money.
