Running it anything but full recirc will hurt your car. Why did you replace it? Stock one leaking? Or just to be (c/t)ool? Go back to the stocker if you can, if not, run 50/50 and I'd recommend buying the forge bypass valve.

I'm going to take a WILD guess and say you didn't research this product before buying did you?

Full recirculation is the only way to go. No questions about it.

Here it is again ANOTHER BOV problem. The stock one has worked fine for me for 138k, I would never put one on my car simply because they just seem to cause problems for so many people and that sucks. I have seen countless threads just like this.

That's not good news. Cancel your order. Install OEM valve. Smoke cigarettes. That's exactly what you should do.

If you have 138k miles, I'm willing to bet its pre 08? The 08+ valves are known to leak at boost as little as 18psi. Granted OPs at 16 and is reporting no issues with the stocker, just sayin.

Personally id keep the stock valve until you start having issues, then switch it for the forg e

Its just a matter of time until the plastic piece of **** starts failing anyways, what's wrong with being prepared? Are you forgetting the 08+ WRXs have the leaky plastic bpv's?

Yea I have an 02 WRX, I never heard about a leak problem with the 08. Thats unfortunate tho that they have that problem, seems like an issue for the almighty SOA! Why would they make that out of plastic in the first place? It seems like a problem to me but it doesn't suprise me with Subaru, It's like why would you put a cat in the upipe of the older WRXs?

yes it does...do not run full atmosphere unless your tuned respectively for that setup. You may run at most a 50/50.

Everytime a fully atmospheric BOV dumps on a stock setup...it causes the motor to run extremely rich as your still sucking in air from the turbo and the MAF is measuring that air and thinks it is to be used when its actually being dumped. So now your pissing fuel into the motor that isnt being combusted so it washes down your cylinder bores, chews up the rings and thins out your oil. Whereas a recirculated Bypass valve does just as its name suggests ...recircs the air in a loop until the air is needed again....this way it is not sucking in anymore metered air (or if it is, it is very minimal) through the intake until the throttle is opened again.

just a side note, you really don't need to replace the stocker unless you are pushing more than 20psi... 16psi is pretty much stock.

I'm putting out max of 20, tapper to about 18.7
No leaks, no issue with stock bpv.

My 09 starting leaking so I just bought a Tial QR, works great. If you want the psshhh noise just get a CAI. It sounds ten time better than a stupid squeaking noise anyway.

I've ran (and I'm still running) GFB 50/50's for several years on several cars without incident.
