Yes, forcing air into the engine bay without having any means of letting the air escape will cause problems. Imagine that your pumping air into a pressurized tank, normally these tanks have a blow off valve so that the excess pressure can escape. Without heat extractors you're running without a blow off valve. If you continue to pump air into the tank, it will eventually explode.


EDIT: as the above poster mentioned, it *may* not be enough air to matter. But the same principle applies.
