Default Hissing noise from the intake?

I heard a hissing noise (coming from what I can tell) the back of the intake. Has anyone done one of these on a 4.0l? I have looked around the forum but have come up unsuccessful in finding a step by “step or how to” thread to assist me. I don the want to dive in blindly if I can help it. Has anyone replaced an intake manifold gasket on a 94 4.0l and been successful? Any help will be appreciated!

I would not be so quick to remove a part that may or may not be the cause of your problem.

You need to verify the source of the leak. ( it could be just a vacuum line )

If you find the leak is the intake, I highly suggest getting some sort of factory service manual or online subscription to Alldata or Mitchel on demand.

A good service manual will have service procedures and specifications you need plus it will include TSB ( technical service bulletins )

You will also need a good quality calibrated torque wrench and a good amount of basic hand tools to replace the intake gasket if needed.
