Engine or Turbo making weird noise

[azbassin]

Hey I'm new to the forum I have a 04 f-250 with a 6.0 in it and it had like 87000 miles on. I was towing my boat and this past weekend while going up a hill the turbo or engine started to make a weird noise and loses some power. It wouldn't make the noise at first while going up the hill but after going up a couple hills it would start to make the weird noise and lose some power. Then I would let out of the throttle a little for a while and it would go back to normal. The oil, coolant, and engine temperature didn't change but i don't know what the turbo temperatures were i don't have a turbo gauge. any help is much appreciated

need a little more detail on the "strange noise".

Did it pop, did it squeal, did it whine or drone?? All helpful information. Did it change proportionally with the RPM of the engine, or the load of the engine?

What were your oil temps and coolant temps during the condition?

It could also be a blown or torn boot on the CAC tubes on a 04 the drivers side will be plastic unless it has been changed out, this is also known to split. The passenger side is aluminum. Each has 2 rubber hose looking things (boots) clamped onto the tubes.

These will sometimes get oil saturated and blow off makeing a whoooing or whooshing noise and loss of power.

it was more of a drone noise, the load was the same it would just happen while going up a steep grade for a while, it happen while going through the mountains. The rpms would stay the same but it seemed like once it started to make the noise it would drop a couple hundred rpms. I'm not sure what the temperatures were it just has the stock gauges where it shows if its getting hot, i just checked one of the boots it is covered on the outside with oil is that what you mean by saturated or it has just absorbed a lot of oil?

Yea thats what I mean. Only look for the oil on the inside the boot. Oil makes the rubber softer and it can slide off the tube under accelleration. If the clamp was positioned near the end of the tube it will actually slide back in place sometimes and look ok. Give it a had tug and see if it comes off.
