To remove the old one has to be broken

LTZ 2.0 etc.) breaks old PCV apart. In addition, it is difficult to use a connection tool to remove the PCV hose. Old PCV hose tends to break at the plastic bend, so a new PCV hose is required! To remove the old PCV hose from the turbo, you will need a 5mm allen wrench to remove the metal fitting bolted to the turbocharger. All in all, it's quite a complicated process to complete a simple task.

Pros
  • Manufactured to GM OE specification for fit form and function
Cons
  • Requires socket
