if i recirculate with a greddy bov, will it give off any noise?
What's up all... I recently picked up an 02 wrx sedan with some upgrades. I am not really sure what the previous owner has done to it because I bought it from a dealer. From what I can tell it only has a few performance upgrades including a TXS bov and a Blitz nur spec cat-back. I am pretty sure that it has some kind of suspension kit because it looks like it sits a little lower than stock (although it does have RSL 18" elites) .
The main question I have for you guys is; is the bov worth keeping or does it do more harm than good? I like the sound, but if it really is hurting the engine then I will just go back to stock for now. I have read through the stickys in the forum, but I would like some opinions on the subject. Please don't bash too hard, it's an honest question.
By the way, I will post pics asap.
Most people on here will tell you that you should go back to the stock bypass valve. If you like the sound of the blow off valve, i would suggest you remove the intake silencer when you re-install the stock bpv. This makes the stock bypass valve more audible. If you search, you will find instructions on how to do remove the intake silencer.
why is it that every noob seems to miss the sticky that covers this exact topic, and many more??

Although I am no expert on these engines, I do not see how an aftermarket bov would hurt the car. I could see the possible decrease in gas mileage, but to harm the engine by simply depriving the engine of air (richening the mixture) is what I don't understand. Is there something else going on that I am not thinking about?
No offense to Chromatica, but this is an honest question in which I am looking for additional information from what is posted in the short section of the sticky.
Like a few guys already said, your best bet would be to go back to the stock BOV until you need a new one. Some people run BOV's without problems, Some have alot of problems, I had the Rfl bov on my WRX when I was stock and I would turn on my car and it would stall right back out sometimes.

not flaming, but the facts of the matter are simple: stock bov > aftermarket....for a variety of reasons. But do as you wish. "to each, their own"
