I don’t know if anyone remembers, but a while ago I was having issues with a loud squealing noise coming from my engine. I took the car into the garage, and after hooking it up to the laptop they said they couldn’t see what was wrong with it. The only clue was that the noise stopped when the oil filler cap was removed.
I put this into ChatGPT, and it came back saying it was 99% sure the issue was a faulty PCV (Positive Crankcase Ventilation) valve. Turns out it was right. I asked the garage to replace it, and since then there’s been no noise at all.
Just goes to show—unless it’s a dash light or a computer error code, the art of modern mechanics diagnosing issues themselves seems to have disappeared.
