: PCV Rattle

My PCV is rattling like crazy....almost to the point of a buzz.
Is this normal?

If you're talking about the PCV valve, it might need to be replaced if it's making noise more than usual. The spring can become detached from the weight or they can get crudded up with oily residue, either way it's only about a $3 part and takes a few minutes to replace with no tools. If I was you, I would just swap it out with a new one and you'll probably be just fine.
