Why is my Ford PowerStroke making a high pitch whistle noise?
It happens at low boost pressure and seems to go away when it builds more pressure. I’m getting lots of boost when the engines working it will give about 25-30 psi. I ordered new intercooler charge pipe and boots as mine was in terrible shape, replaced those parts last night and I’m still getting the noise.
What does a high pitch whistle sound like?
Recently noticed upon acceleration I’m getting a high pitch whistle, almost sounds like a dog whistle. It happens at low boost pressure and seems to go away when it builds more pressure. I’m getting lots of boost when the engines working it will give about 25-30 psi.
Why does my Whistle Go Away when boost is low?
Usually a bellows or CAC leak will affect boost at least a little. A small leak at the downpipe can cause a whistle under low boost, low RPM, low load conditions. I know this because I had/have one. Still unsure if it’s fixed or not, since I still have a similar whistle that goes away when boost gets over about 5 psi.

What are the issues with the ZD30 engine?
The ZD30 engine has suffered a poor reputation for premature failures including melting/cracking pistons and overboosting, largely due to some common issues. These engines run a variable vain turbocharger with boost controlled by the ECU, and to meet stringent European emission standards run an exhaust gas recirculation (EGR) system.

Why does MY BMW engine make a whistling noise?
If impossible to spot by mechanic – drive till symptoms increase otherwise guesswork likely applies (not recommended). P.S. Mixture fault codes need to be questioned and live data examined; if mixture adaptation limits at idle exceeded, then your engine likely developed fault with block ventilation valve.
What’s the engine whistle noise on a Honda Element?
Mine starts at around 35 goes to 40-42. Honda gives me the brilliant answer of that nothing. Well at one point it was nothing meaning that sound wasn’t there. It started around 20 to 25k on the odo. So I found this site justanswer.com. Supposedly the people answering are verified mechanics.
