To much boost

[BigRAWesty]

When the engine is off the vnt arm on the turbo will down..
Then when you start the engine it'll lift..
It's how the vacume vnt turbo works..

The reason for hearing the leak is you know the factory snail can make 25 psi. .
His dawes is right in so max boost. Still only making 13 psi..
That's one hell of a leak..

Yeah still, depending on where the leak is too. My original IC in my ol'ZD was leaking and I couldn't hear it....

Vac leak, stuffed vac pump or possibly shot turbo vains..
Take the actuator off and see if the turbo vnt arm moves freely..
If not new turbo..

When i take the vac hose off the actuator there is suction on the hose.

Could the actuator be stuffed?

I think your looking to hard into this right now. Test the IC first for leaks. Then worry about the next step.

How do i test ic?

Does a radiator repair shop do this?

Sorry for all the question, just want it fix, im sopose to be going away in 3 weeks.

Seal both end of the ic up with duct tape or the same. Then submerse the ic in water with the inlet and outlet above the water, then use a bike pump with one of those ball pump needle thingo's and push it through the tape and pump air into the ic. If you see bubbles then its leaking. Or just take it to a radiator mob....
You need to do one thing at a time otherwise you will just get lost in it all. Make sure the ic is good then move onto the next thing. Resetting the dawes and needle valves.
