Is my turbo fried

[jturnbull]

ok so today i was driving on the highway boosting a good 17 psi then all the sudden something happened ant the gauge read 0 psi when full throtle and 2hg at idle i cant hear it spool up either i have a stock turbo with 123xxx miles on it is it gone?

[aytheory]

vacuum problem probably - not blown turbo - because even with blown turbo - vac is usually normal

[jturnbull]

would i be able to fix this with a boost leak test?

Check hoses

[audiness]

wastegate may have also let go

#1 visually inspect the engine compartment. Make sure no hoses popped off. At 17psi vacuum lines that don't have clamps on them can pop off.
#2 if you can't find them that way, start the engine and listen for the vacuum noise. Sounds like sucking air.

It's possible that it's just the vacuum line going to your gauge, or even the gauge itself. I know at least one of the members here have had issues with their GlowShift gauge.
Try another gauge, and connect it straight to the intake manifold. Should be 18-21in Hg vacuum at idle.
I guess it's possible you managed to get a gigantic boost leak, but I don't see that being the issue.

Wastegate is a good thing to look into as well, try a handheld vacuum pump on the actuator and check if it's leaking down.

You guys are dumb, If the car runs fine and feels the same, which is what im assuming, then its probably a messed up boost gauge. You would feel a huge difference in performance going from 17psi to 0.

[jturnbull]

its not the gauge the car is slow as balls there is deffinately something wrong

[Militant-Grunt]

Unless you're bellowing white smoke out the exhaust you didn't blow the turbo. A precursor to a turbo is going bad is a drill noise.

[docurley]

Have to agree sound like a vacum. issue

Check everything that connects to the intake manifold because it is no longer sealed which is why your not producing boost or a good vacuum reading.

[MultiAudis]

pardon the threadjack, but the exact same thing just happened to me, however I am still seeing the 18in hg in vacuum, but zero boost... no smoke or noise from turbo... not really sure what direction to go either...

[Mawhitey]

He needs to look, it could be anything from a vacuum problem to a snapped shaft,I tend to think boost pipe off

Usually causes the car to stop running.

Mine still runs and drives w/ the DV stuck open and the recirc line disconnected, or rather being eaten by the A/C belt. Idled like hell, and throttle response was non-existant, BUT it ran

[jturnbull]

yeah i mean at idle its like -1psi then when its full throtle its 1 psi i am going to take a look at all the vac lines anyone have a diagram by chance i know people say its under the hood but its not on my car

[jturnbull]

ok so this is what i found its on the passenger side almost directly under the turbo

Mike, did you get my PM?

[mike-2ptzero]

Mike, did you get my PM?

Yes, waiting for someone to call me back about it.

[.Mad Hatter.]

awesome, thanks alot.

Next step is finding out where it came from...

Look for hose connections to the turbo.

This happend to me. The flap on my wastegate broke and i couldnt hold any boost. The car ran fine just slow as hell.

[MultiAudis]

that sounds exactly like my issue... how do I check the wastegate?

[jturnbull]

it was the line from the manifold and i connected it and its back to normal
