Review on 🔧 Fram FV408 PCV Valve: Optimize Engine Performance with Positive Crankcase Ventilation by Ronald Cambridge

I can't stop talking! Maybe it was defective, but complaining and sending it back is not worth it. Replaced it with an OEM Mopar PCV for just a few dollars more. 2005 Grand Cherokee 7/3/10/2/2020 - Should have heard my own review. With a bad memory, I bought the same one for another Jeep Grand Cherokee, this time a 2004 4.7 v8. While not as bad as 3.7, it still wobbles on 4.7. Mostly idling, warm or cold engine. I don't remember the 3.7, but the 4.7 has an insane amount of flow through the PCV system, probably beyond Fram's capabilities. I have ordered Mopar OEM PCV again. Currently. Let's see if I really remember that time.
