Had a day last week with a Detroit 60 that taught me something new
I was working on this old freight truck from a local dairy, been in the shop before for the usual stuff. Last Tuesday it came in with a weird surging idle, I was about to swap the injectors. Turns out the gear train timing was off by 2 teeth, been like that for probably 100k miles. The old driver said it always ran rough but 'never quit' so they ignored it. Has anyone else found something like that where a simple timing check saved a ton of guesswork?

Nah, just swap parts like everyone else and move on to the next job.

Did you ever feel like you had to fully diagnose every failure before? I used to think that way too, but honestly swapping parts and moving on saves so much time. It's just not worth digging into every little thing when a new part gets the job done.
