2002 silverado 1500 5.3l about 80k miles

Replaced the PCV, when I took it out I looked at it and was astonished. It was the same size as my replacement, but the inside was totally different.

Replacement: shiny silver metal, makes a distinct clicking noise because of the pin inside

Old PCV: Totally empty. Hollow. Plus, the hole at the bottom (where you would stick your thumb to test suction) was just a pin-hole.

Wtf?

Guy at hardware store told me it probably "collapsed", and confirmed I had the right piece for my make/model.

Did the pin get sucked into my intake system? Come to think of it, I do remember hearing a "rattling" sound like a marble if I ever go full throttle (to pass a car in 2 lane)
 
Sounds like pinging to me.

Your PCV valve may indeed have failed, but I doubt it's related to the noise you hear when passing.
 
interesting, i wonder what happened to the rest of it, hah! other then that my truck has been running excellent
 
Sounds like you originally had the orifice type, which really cannot wear out. It's just a hole of a calibrated size. So I would clean your original one, and put it back in.

yep, I saved it and am going to clean it up.

It's not that dirty, but the grommet was pretty nasty so at least that is replaced =)
