Hello all! Iím trying to get some advice on my bus. Itís a 2000 E450 7.3l diesel engine with over 200k miles on it (the actual mileage is unknown). Iíve been driving it for a while with no real issues. Mid August, it drove from California to New York with no problems! Then, it sat for about a month (I know, thatís my bad). I went to start it up, drove about a mile, and then started to notice a weird sound.
It sounds like something mechanical, almost like gears not grinding correctly. There is a squeak, which made me think there was an issue with the fan belt; but the squeak isnít constant. Both the mechanical sound and the squeak only happens about once every 30 seconds, but not constantly.
I made a video to try and capture the sound: https://youtu.be/ro5EgEO5voQ
Iím not the most car savvy, but Iím learning! Any help would be greatly appreciated!
