Replaced mine at 130K miles. Didn't see any differences at all including my oil consumption. She's as thirsty as ever and I have run a catch can for years. Don't believe the hype they help the OC issue, they just catch the blow-by.
I replaced mine and there was no significant change. They can cause oil leak issues at least on other cars where it's this intricate setup like on an Audi or Volvo. Where a new PCV setup is about 300 dollars or more to replace all the hoses.
I'd think you see more of an oil leak problem with a plugged PCV vs an OC problem. If it gets plugged up all that pressure builds and the oil has to go out somewhere. I have heard the G does have PCV galleys on that side of the VC, which can get plugged up. But, haven't actually heard of it happening to anyone.
