Hey guys, my 2000 xj sounds like it is blowing/sucking air. It is very audible, and with the hood popped i think it sounds like its coming from the intake manifold. Are there any vacuum lines around there, or could it be sucking air if the gasket is shot?

I am stumped

Are you trolling?

A monkey could look over the vacuum lines and find defects.

Do you have any type of intake? Could be some connection leading to air filter, causing air to leak.
