is it true stock bpv goes bad after 20k+ miles?

[lestat13]

10 minutes if you take your time. It's 2 10mm bolts and 2 hose clamps. It's right in the front too. It's too easy to replace and works much better than the stock valve. @ $150, it's also easy on the wallet. I'm put off by the forge ping but it works well. I deal.

I also hate the forge ping, but a few people said theres doesn't ping.....

What do you mean by changes the drivability? I personally think the stock bpv is sufficient and its only when people have leaky BPVS that switching it out renders improvements. Also, I bet the added sound of an after market BPV is probably having some think theyre getting more power when actually theyre not unless of course they started out with a leaking one.

Has nothing to do with sound. Boost response is much improved. With stock BPV on my Prosport electric boost gauge 16 psi tapering down to 13. With Forge BPV (blue spring) 17 psi tapering down to 15. Did I mention my stock BPV only has 600 miles on it!(rlaugh)

If you look at the hot side piping and maybe give it a sqeeze, it might be soft. It really should be very stiff or boost will fluctuate. also check all your intercooler clamps for tightness, mine were loose. They should be tclamps anyways. And that is a good spot to leak at. Then the two bolts that secure the valve. just to be sure. Check torque spec though. About the 20000 mile wear item, i am not so sure though

If the stocker goes bad and you are leaking boost, all this really affects is power right? It won't HURT the engine itself or the turbo, will it?

 

[parkerfe]

Just get a BPV and feel the difference. I can't believe the difference in boost response between the stocker (mine has about 600 miles on it) and my Forge. Car with the stocker feels like a freaking Buick.(pissed)

FYI, a Buick GNX is a very fast car...

Even according to a Ford engineer, it is simply a 20k part. The flutter valve is plastic, and after so long of letting excess boost go during normal throttle, it starts to wear the valve out, thus letting more boost than it's supposed to.

It's covered under emissions warranty. He basically said that you'll hear it get louder and louder over time.

So is there a TSB on this, or is just hearsay from a guy you know?

**** yeah they are

This is from a conversation I had with a Ford engineer who was visiting my dealership when I was buying my MS3. He was there purposely to take notes and investigate the setup of the BPV on the MS3.

**** yeah they are

they are fast and they are cool. But my 07 Mazdaspeed 3 is faster for sure and quite cool imo. Respect to the Buick and its turbo!

turbo sticking out the hood and the camera can't even handle the badassness of that turbo sound

Whether or not he actually did what he was supposed to, I'm not sure. I just know he came in representing Ford with a engineer access badge, and asked to look underneath the hood of a MS3. And we got to talkin!

 

[ericrapp]

Pure sickness with the utbe vid. Thanks U. I will be watching you tube GNXs tonight it seems.

 

[ericrapp]

I was half kidding Silver. That is pretty cool. Any thing mentioned by the Ford guy that might help us understand the cars design intentions a bit more?

 

[phillyb]

holy s*** that buick is insane.
i replaced my valve at around 16k
and honestly, i would like to have all of the valves...greddy/forge/hks/synapse. i would like all of them

Naw I wish. I was too excited about the car to stop and ask more.

I DID meet someone today who runs a supplier for Ford. We talked a little bit about the MS3 and the turbo setup with the floating bearing seals. He said they've been running a setup like that for a long time, Saab's and whatnot. It's a reliable setup really, and efficient from what he tells me. Also said I shouldn't really have any problems with the turbo itself. So that was encouraging!

Well I'm at 37.5k miles and still have the stock bpv. I've been checking boost with the dh lately, and it seems to be holding just fine (~16-18psi in 4th, 5th, 6th). I even get 19psi spikes sometimes in 5th and 6th. So I'm not too sure about 20k claim.
