Turbo whine on an older diesel has me debating repair timing

Honestly, last week I worked on a diesel pickup with a loud turbo noise. Tbh, one mechanic friend says to just keep an eye on it, but another argues it needs fixing right away. Ngl, I've seen turbos hold up for ages and others fail fast. Where do you stand on letting turbo noise slide versus immediate action?

If you said they can fail fast, I'd check for power loss too, not just the noise.

Read a case study where power loss, like @singh.vera said, was the real culprit.

Fail fast" is like that weird noise my fridge makes.
