If you like it, leave it. I was just letting you know that it basically creates a vacuum leak.
For a PCV system to work properly, there needs to be a place for fresh, filtered air to enter the crankcase, and a place for it to leave (PCV valve). These two locations need to be as far apart from each other as possible. Most engines have the air enter in one valve cover, and exit out the other valve cover, but the design of the intake manifold on the EFI 5.0 engines makes this difficult, so they moved the PCV to the rear of the intake manifold.
Take care,
