The sound only happens at a Idle, not while driving, Sounds like opening a big valve on my ar compressor tank.

PS why are there spiders in my engine :-)

 

Thank you too bluescrew !!!!

 

I'm not into cults...outside of PSDs and Guns, anyway!

Sounds more and more like a faulty EBV solenoid in the turbo pedestal. Does it do it all the time or only when cold? Louder in the engine compartment or tailpipe?

The EBPV/EBV (Exhaust Back Pressure Valve) is a solenoid that closes a valve in the exhaust housing in the turbo, creating pressure and helping heat it up a tad quicker. It is SUPPOSED to only open when idling, and below certain temps. Sometimes they leak, stick open, etc and can cause the valve to close when it's not supposed to.

You can try unplugging it (truck off/cold) and see if it goes away. It is the only electrical plug in the bottom of the pedestal under the turbo. In my (and many other's) opinions it's not really needed. It's not uncommon for people (like myself) to delete them completely in lieu of fixing them. I will upload some pics in a second.

 

This is the pedestal, (out obviously) The plug is the white-ish connector in the bottom right in the pic. The rod/solenoid that controls the valve is in the bottom left hand side of the pic, pointing towards the camera.



This is the actual plug itself. Just pop the clip off and pull out. Mune is just hanging in the valley tied out of the way.



This is the actual valve that closes and creates the back-pressure.

 

Newstang- Does the air noise stop if you tap the brake pedal at idle ?

 

Haven't tried it I just let it run in the lot, and it eventually just stops.

 

Ah, Guns! Now were talkin!
I'm former NYPD, Have lots :-)

 

Kinda like a Jake Brake? It only happens at Idle in the Driveway that I noticed. Just sounds like allot of air then after a while , stops.

 

Similar, yes. But it is designed/intended for use at idle to warm the truck up.

Next time it does it, try tapping the brakes.

Also, check the RPMs, (are they higher than normal? goes down when you hit the brakes?) and what temps are you seeing it come on at?

 

Newstang, No Mac interface for AE. which sucks. I to am a recovering Windows user. Dropped Bill Gates about 2 yrs ago. got tired of having to pay $$$ every time Bill decided to rearrange the "furniture" and rename the product. I still have an old Toshiba that I run my AE on. I don't want anything Windows even near my Mac.

I too have a "real" computer (Mac) and i just use Parallels to run AE, it works great.

 

What is this Parallels you speak of Kimosabi?

Barney

 

It allows you to run the Windows software on the Mac. Basically allowing two operating systems to be installed.

 

Precisely. I only use it for Microsoft Streets and Trips, (unavoidably necessary for work), Auto Enginuity, and DP tuner's F6 software. The nice thing is, the Windows side is totally separate from the Mac side, so if it has issues, you simply erase it and re-install it. And the ample computing power of the Mac allows one to run both systems concurrently without a hitch. Pretty cool....

 

Yes, the ample-power... that they bought from Pentium....
