Factory BPV - Leaks

I've always viewed running VTA on a MAF car not tuned to it akin to drinking alot of natural juice. Its not bad. Its just not good, either. Almost any BOV can be set up to run recirculation, and for the most part its about five seconds worth of work. If you want to try it, you could run VTA for a day or two, and if you don't like it, its as simple as plugging the recirc hose back in.

yeah if you are going to buy a BOV, make sure that it includes an adapter to run in recirc mode if there is a problem. My biggest piece of advice to those who are running VTA, please get your car tuned. If you dont do this it could cause a lot of problems, especially with stalling and stuttering when you're not on the throttle and general loss of performance. That wikipedia article really described the process well, very quality post.
 
I would hope that form follows function in this community...i.e. get a part because it is built well and helps extract more power, not because it just "sounds cool" (and might cause decreased reliability/power).

hope all you want, people still set their BOV to vent because it goes "woooooosh!" lol
 
Hmmm, not buying a valve that increases performance due to the sound it makes is the same as buying one just for the sound. You're keeping the stock valve which leaks or paying an additional $100.00 for a valve just for the sound that they make... or the sound that they don't. Same thing.

i dont think anyone was denying the fact that the valve was beneficial, just saying that with VTA, a tune would be practical and help avoid problems, buying the valve just because it goes wooosh and forgetting about the performance end of it is what we were criticizing
 
I think you'll all be interested to hear this:

I was about to leave the dealership after taking a test drive when I seen someone who introduced themselves as a Ford engineer to my salesperson, and asked to look underneath the hood of an MS3. I had mentioned earlier how I had heard the plastic BPV's leak, and my salesperson said he hadn't heard anything regarding them.

Having just know been told by me, he introduced me to the engineer and we got to talking. He informed me that the plastic bpv is basically real cheap, and the flutter valve is weak, to the point where it'll eventually start to wear out and stay open or leak boost. He informed me that Ford is planning on using a boosted 4cyl setup very similar if not the exact same thing the MS3/CX-7 has, but they were investigating that problem first. He started laughing when I asked about "EcoBoost" and told me he "couldn't go there."

The plastic BPV is considered by Ford as only a 20k mile product, and at one point you'll start to hear considerable more noise from the unit itself. It IS covered under warranty as an emissions based concern. So if you have an 07 MS3, it could be justified to your dealer to have it replaced.

I was told really not to put it out there about this issue, since they are still working on a fix but I figured it's better knowing that Ford is stepping up to take the necessary steps to fix this issue.
 
hmm very interesting indeed. It kinda sucks that they made them so cheap, I was already planning on it, but now almost surely I will shop for a replacement BPV, probably the Forge unless something better comes along. thanks for sharing!
 
Yeah he said all the components are plastic, and that flutter valve just wears out so fast during normal driving because it sits and pedals away letting excess boost leak while you're only part throttle. After a while though, it wears to nothing.

I'd go visit your dealer if you can point out that it's making more noise than it should. It's covered under warranty.
