Ok so this is a better video of my idle issue this is with the car in neutral.


The bov makes a whistle if i barely blip the throttle... someone said the spring might not be right? Also I have the bov T'd & I just read it had to be straight to the Intake manifold? where should I route it on the manifold without having to T it?

boost leak shows nothing but the valve is closed while the car is off.....

 

Vid isn't working for me?

 

Sorry forgot to make it public its viewable now.

 

Do you have a popcorn machine inside that evo ?

 

It's the sunroof, I removed the headliner to fix the motor. It's very noisy...

 

Does it leak at idle with the car stationary, and is it vta or recirculated ? If its vta and your still on the maf theres your problem right there.

 

Yes it still leaks while stationary, just tends to do it more while im rolling, @ first I thought it was the brakes squealing but they are new & it makes the noise with just a little 1500rpm blip. I can put a piece of tissue paper by it and you can see it blowing it.

VTA & yes it is on stock maf .... I know its suppose to be recirculated..... but I've had my last car tuned with the same setup, & it never leaked @ idle. Someone told me to "Shim" the spring inside to make it sealed a little better?

The car had a VTA bov when i purchased it. Owner said it was tuned but when I looked into it. Everything was stock on the ECU not even boost cut % where changed ever.
