If you do that, you might want to place some kind of filter over that hole. I believe that tube belongs to the PCV system and pulls filtered air from the airbox. You might also want to check and/or replace the PCV valve.
The PCV system pulls filtered air from the airbox, through the tube you were describing, through the crankcase, through the PCV valve and into the intake. If the PCV valve is bad, the crankcase will vent out the tube into the airbox, or if that avenue isn't open, through some other means. Which can be bad as those other means tend to be through seals which you want to keep in place. Good luck.
