I own a 1997 Chevy k1500 5.7L v8 with 248,000 miles. There is a whining noise coming from the engine. The noise sounds like it’s coming from the back or the middle of the engine. I think it could be a vacuum leak but I’m not sure if it is.

Usually only the pumps make a whining noise but it could be vacuum leak. This is how Scotty finds hard to locate noises https://www.youtube.com/watch?v=Wy5nqh3LSs4
