2013 INTERNATIONAL PROSTAR WITH MAXFORCE 13 MAKING WHISTLE SOUND WHILE ACCELERATING.

Please Help! The Truck makes Whistling/ Sqealing sound while accelerating loaded or not Loaded. It goes away when I take the foot of the accelerator. The more the rpm the louder the sound. This Morning when I started driving it was also smoking from the exhaust pipe while driving. It came from undeothe Truck but went away after 10 minutes. The power is good. I don’t feel any difference in the power while accelerating. With engine break on and foot off the accelerator it makes the noise but when I shut the engine break off and take my foot of the accelerator the sound goes away.
It all started after I heard a load POP Sound.

 

I had one do that and it was a improperly sealed gasket on one of the turbo hoses where a mechanic didnt put it back together good could have a broke seal or clamp somewhere

 

I’m going to look for that. Let me see what I can find. Maybe I can share some pictures. I took to one Mechanic shop and without looking at it they started to stress the Turbo so I left.

 

There is oil and soot on this pipe between the turbo. But it’s been like this since I changed the gasket. Little more oily than before.
Anything to do with that?

 

I believe this is where the actuator is. There is a lot soot here. This has been like this for almost a year now.

 

This is where the smoke was when started the drive in the Morning and it webt away after 10 minutes.

 

Oil leak?

 

I don’t see any oil leaks besides that between the turbo pipes but it’s been like this for 7 to 8 months since I changed the turbo gasket.

 

Whistle noises are usually the first sign the high pressure turbo is failing. All your pictures show normal and minor oil leakage. The first picture is simply the oil drain. The second picture is of the crankcase oil separator, also normal to leak a bit of oil. The exhaust flex pipe probably had moisture around it and that is what you saw. The piping should be removed for the upper turbo and compressor wheel checked for radial and lateral play.

 

I am going to gehring T you you will start blowing coolant out of the engine your EGR valve will go down with your EDR coolers you will have them replaced within a week or 2 your fuel pump will go out and blow metal author the engine your 2 estimates will be for the 1st EGR AGR coolers will be $5500 your fuel system will be 14500 I just had it happened to me with a sane exact symptoms
