doogs8282 Member 22 Member For: 16y 8m 14d Posted 13/09/12 07:34 AM Share Posted 13/09/12 07:34 AM Hey guys, I'm in the middle of purchasing a 09 XR6T from a dealer with 97k on the clock. I noticed on the test drive that there is a distinct vacuum/air/ boost noise coming from behind the dash and gets stronger the harder I push. It doesn't seem to impair performance or idle, it's just noisy, not something the stereo could or should drown out. I've driven probably 3 FG turbos so far and none of them had this issue. So the dealer took it down to ford I get looked at and they couldn't find anything (nothing loose or cracked in the eng bay) and said its normal. The dealer I'm buying the car from actually drives a G6ET, and he knows it isn't normal, so he is looking into it himself. Any pearls of wisdom as to what may be causing this? I was wondering if the guy who owned it previously had extra gauges mounted and removed before sale and there is an open line begin the dash.... It's that loud...Thanks guys!

I'm meant I be picking it up tonight, so I'll check the air box. Thanks! Link to comment Share on other sites More sharing options...

Looking at worst case scenarios, whatever it is shouldnt be causing damage from what I can gather, just annoying; mabe I just settle on the car with a cash adjustment and slowly nut it out myself...I just want to be fairly certain that somehow its not causing something stupid like a lean out condition... Noises- I can live with for a price, engine damage I can't. Link to comment Share on other sites More sharing options...

He sealed it and the noise is apparently much less, but not gone, anyone else had a similar issue and short of shelling out for another booster, is there a fix?

doogs8282 Member 22 Member For: 16y 8m 14d Posted 14/09/12 08:41 AM Author Share Posted 14/09/12 08:41 AM After a bit of looking around online, I see that fg LPG models had a recall due to vacuum leaks associated with the brake booster and it's check valve, but nothing really to do with the petrol falcons. I wonder if it's only a batch of bad ones that only went on the LPG ones, or it shows up more on those models. Sounds almost too similar to be coincidence.
