Forge BPV Awareness
So I am not writing this to bash anyone or Forge. I understand that not everything can be perfect when being manufactured, I was one of the unfortunate unlucky ones. I am writing this as an informative thread to other members that may have boost leaks, and/or to inspect the product when you receive it as best you can.
I've had the Forge BPV for a few months now. Occasionally I would hear the screeching sound you get when you pinch the end of the balloon and let the air out. I first had swapped the IC to TB hose out because that had leaked once before. Which it was probably one of the factors because the end of the stock hose had a crimp in it. I replaced that with a silicone hose. Occasionally still hearing the leak. So I took it to my local performance shop who did a boost leak test and immediately found the issue. The leak was coming from the BPV at the base of the cylinder where it connects to the flange. I took the car home pulled it off and put the stock BPV on until I get a new one. I have posted some pictures of the BPV and what I found to be the problem. After I got the BPV off I closely looked at where it was leaking and there is actually a gap where the two parts meet. So it was leaking the entire time, I may not have heard it every time because the gap was big enough where the air could pretty freely flow out. Other times I think the air pinched the o-ring in it to cause the screech because the gap was made smaller. Mind you I have never taken it apart from where it was leaking either and it was leaking from the day I put it on, so it wasn't user error.
Hopefully this helps someone out there. As I stated previously, this wasn't meant to bash anyone or Forge just wanted to create some awareness to others. There are plenty of people that run this product that have no issues.
