Re: [AMC-List] Original PCV valve?

Yes, They do actually wear out.
Take an old one apart and look at it.
The dirt, grit,moisture that build up in them wear way the edges and flat surfaces till they rattle and don't seal well. 
  I've seen/heard some that sounded like bad lifters and the flat valve was work over halfway thru.
