An oddity I’ve discovered barely today on the truck. Can’t say I’ve ever heard this before. Narrowed the sound down to be coming from this PCV valve on the driver’s side. But what could it mean? Has anyone ever heard this sound before? Sounds pretty scary but not sure if it’s a problem with the hose or the valve itself? I should add, I can feel the hose vibrating too.

WARNING! Audio might be a tad loud. Here’s what I’m experiencing.

 

PCV valves are relatively cheap. Replace it with a MOPAR PCV valve (not an aftermarket PCV valve) and see if the noise goes away.
