Good point! I never thought about the possibility of both issues being linked. In that case it must be from the engine, not the intake, you can't really hear it outside of the car.

Where do you think a vacuum leak would most likely occur? I feel like it could be valve seals or maybe an intake gasket. I soooo look forward to having some real income in the next few months, the cam and everything is going to be great but having peace of mind that my internals are in good shape is even better.
