Hi,

The leak could be in many places. If it is that loud, check where the air intake tube between the radiator and throttle body is fully attached and tight.

Also, here is a link that explains how to locate and repair an engine vacuum leak:

Let me know what you find or if you have other questions.

Take care,

Joe
