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

Thanks Heavyd! The CAC hose by the Turbo had a little hole in it so I got that replaced. The whistle sound was gone but this Morning when Started to smoke from the exhaust pipe underneath the Truck.
What could be the reason for that? The Mechanic said the whole exhaust pipe from the back of the engine to the back of the truck needs to be changed, but he didn’t open anything to check anything.
Could that be the oil leaking from the exhaust has kit?

 

You were right. There was whole in that hose in the Turbo side. So I replaced it but this Morning it started to smoke from the exhaust pipe under the truck when I first started the Truck and then it went away after ten minutes. The Mechanic said that I need the Exhaust pipe from the back of the engine to the back of the Truck. That whole piece without looking at it. It smells like burning oil.

 

Hey Heavyd... I’m having the similar issue again. I was having a whistle sound for past 4-5 days but there was no drop in power or boost. The whistle sound got louder with foot on the accelerator and went away when I took the foot off the accelerator. This Morning I heard pop like how a belt breaks and a grind sound after that for 2-3 seconds and then it went away. The whistle sound stopped and the power of the truck dropped about 50% and I see a boost gauge only showing about 10% of Function. Can you please help with your input. It is always greatly appreciated. I’m on the Road right now. I hope your input can save me some money like always.

Thanks

 

I believe this is the actuator picture.. there’s a lot of oil there

 

There’s a lot of oil before the Turbo.. Where the CAC pipe goes to the Turbo.

 

Welcome back Heavyd.. did you have a good time? The Mechanic first said that it was the CAC leaking and that was changed today but the truck still have 50% less power. The boost is about 5%. Now they think it’s the high pressure turbo and the actuator, but they checked the turbos on the First day and said that the Turbos were good, but now they think it’s the actuator and the high pressure Turbo. I have noticed the actuator waste gate behind the Turbos isn’t extended on key off or on. Which you mentioned in one of the posts that it suppose to stretch about 12mm. Could this be the bad Waste gate Actuator or the High pressure Turbo? OR do you think it’s both?
