vac problem

[caney]

hi,been posted before but still got this bl@@dy noise in the dash,been told its
vacume related, only chirps away when green boost light comes on,can the boost switch do this ? checked all vac pipes seem ok, motor runs fine but this noise mud skipper had a listen but didant no, help.

[hiroler]

the green light on the dash is the turbo light could it be a problem with the turbo? but they do make some noise thats normal!

[BUSHWHACKER]

If the screaching noise coinsides with the turbo light coming on, then the first place to check is the rubber connections coming from the turbo to the throttle body.
Sounds like you've got a tiny air leak that only appears when the turbo is boosting. Could be a loose Jubilee clip or a tiny split in one of the rubber connectors.

noise

hi, turbo seems ok, replaced most pipes also big bent one,thought perhaps
speedo cable but i think mines electric, its well annoying.

rechecked all hoses even tried it with boost sensor unpluged, no green light but still me birdey noise, whats the two little sensors on the drivers side wing
just before master cyl, vac lines go into it one goes to alternater, can they
make this noise?

Are tou sure the chirp is in the dash? A leaky exhaust gasket around the turbo area will make a chirping noise. The ADD VSVs are on the driver side wing. They switch the vacuum for the front diff.

No need to strip turbo. I meant the gasket on exhaust end of turbo or the round flange gasket a bit further down.
