probably an intercooler pipe has come loose

get a mate to rev the car and stick your ear around where the intercooler is.. you'd be able to hear the air whistling as it escapes from the loose fitting.

Meh each to their own. We've all known since the start that im a ricer, so why everyone is shocked at this purchase is beyond me.

Either way. Rhomel is king for posting two pics of chicks with big tits.
+1 for posting more of them! Lol

Do you find yourself backing off a bit when the auto changes gears so the BOV actually opens?

have a look at the bov in this picture...
its a stock car, but it looks like the BOV is on the wrong way around (like my stock one was originally!)

i dont get it... :?

Ahhh ok, yeah I see what you mean.

Strange..... you'd think the manfacturer would know which way it goes on.

I would have thought the green was around the wrong way, but if your car (which is presumably the blue one) was the same, maybe that is the correct way for the design of that BOV.

Agree though, it does look arse-about. I would have thought the blue engine bay was the correct way (assuming that the pipe running down the engine bay, not the one across it from the airbox, is a positive pressure pipe).

both pictures are just pics off the net... neither are my cars...
but my car originally looked like the green one...


to add to the confusion....

i've put the std bov back on in the direction of the blue car and you cant hear it vent AT ALL... usually you can hear it vent very slightly through the intake system... so now i've changed it to match the green car and you can hear it vent again... :?

i've used the aftermarket bov in BOTH configurations, and in both cases, it vents to atmo!!!

if anyone can explain this to me, it would be greatly appreciated... fucks me how the aftermarket one can vent in both configurations...



just to clarify....
the pipe that crosses the engine is from the airbox to the turbo.
the pipe that runs vertically is from the i/c to the throttle body... (positive pressure?)


so wouldnt it mean that the base of the bov (ie the bass of the spring) needs to be facing the positive pressure pipe? ie the blue car!?


HAHAHAHAHAHA

i need to stop thinking about it... every time i think about it, i get more and more confused until i get the shits with it and just pretend its not a problem... :lol:



oh and back on the original topic of this thread.... on the way to work today, the car backfired three times when i lifted my foot off the gas... imediately it wouldnt build boost anymore..
NO ENGINE LIGHT
i then stopped at the servo to fill up with some fuel...
when i started the car, the engine light remained on... and continued to have really sucky performance...
so i took it to ford during lunch and they said "no error codes have come up. we reset everything and it seems to be fine. if it happens again, we'll have to keep the car for 2 days to do more serious investigations."
eeerrrrrrr, wtf!?
bunch of useless cnuts!! :|

I would have thought so, although if the vacuum was strong enough, I cant see why it couldnt overcome the spring and open the bov on its own.

Either way the bov is plumbed, the bov is just a gate between two pipes, as long as it can still open, the air will still flow from a high pressure area (post turbo to the throttle) to a low pressure area (intake pipe from airbox).

Vent to atmo = you can hear it?

Airbox's do a great job of muffling bov's.


Sounds all sorts of fucked up. If you're having problems after changing it though, I'd change it back to the original configuration, no matter how arse about it seems.

cam: but doesnt the valve only open once the there is a difference in pressure in the pipes? ie when you lift off the throttle...
so if the bass of the valve is facing the firewall (ie its connected to the non pressurised side), then the valve doesnt have any difference in pressure and therefore will never open...
this can be seen by putting the std bov in this position... no sound at all...

but then my question is that why does the aftermarket bov vent no matter what direction its installed... :?

hahahahaha... i think i'm just confusing everyone now... :oops:


yeah, vent to atmo = i can hear it...


brendan: not yet... but the ford dealership is literally 2mins away from my work... i'll have to test it out over the next few days and see how things go...
if things go good for a week, then i'll switch over to the aftermarket bov with the blanking plate on it (ie full recirc)...
then if everything is fine with that for a week, i'll put the trumpet back on...
if the problem comes back, then i'll know that its the venting to atmo thats causing it...
in saying that though, you'd think that if it was such a big problem with venting to atmo that there would be topics everywhere on the net about it, but i havent been able to find a single one on any of the ford forums...

also, a LOT of xr6t guys are running no bovs at all... ie blocking off the pipes all together to get that 'flutter' sound... surely that'd fuck with the ecu more than a venting bov... no?

no, because there is no air escaping the system. Even with a plumb back BOV, no air is escaping the system because its putting air after the turbo back in after the AFM, therefore its already metered air. Although, do these XR6t's have an AFM? the single cam 4 litres didnt... if it doesnt have an AFM, then it shouldnt matter a shit if it vents or not.

i cant tell the difference between AFM and MAP's... to me, it looks like there is an AFM just before the throttle body...
maybe you can check it out on saturday and let me know... :)


for the record... the backfired again last night on the stock BOV... :x
