Noise

2011 International Prostar w/ Cummins ISX 435. I had the clutch replaced two weeks ago and the first week was fine. Last Wednesday night heard a strange noise. Kind of like a long drawn out WHOOOO. Happens sometimes when I apply the brakes and some times when I press the clutch. I suspect an air leak. Can someone narrow it down for me.
 

When it comes to air leaks, I crawl around the truck with a bottle of Windex spraying and looking for bubbles. I have a hearing loss so I find small leaks the most difficult to find unless I use something that creates bubbles.


There's a story how @Skateboard ,backed his truck into a boat ramp and swam around with a snorkel mask looking for bubbles.

After our breathers and liquids discussion, I think I will stick to a sprayer bottle and Dawn solution...
