Got a 6.0 Powerstroke to run smooth after three days of chasing a rough idle
This old Ford F-250 came in with a shake you could feel in the seat. The owner said three other shops couldn't fix it. I spent two days checking the usual stuff, injectors, FICM, even swapped the ICP sensor. Nothing. On the third morning, I was just staring at the engine bay in our Tacoma shop and spotted a tiny crack in the turbo up-pipe, right where it bolts to the manifold. It was so small you could barely see it, but it was letting in just enough unmetered air to mess with everything. Replaced the gasket and that rough rumble was gone. The guy picked it up and called an hour later saying it drove better than it had in years. Ever have a problem that was just one stupid, hidden leak?

A tiny crack in a pipe can't cause that much trouble... can it?

Bro you'd be surprised. Had a pinhole leak under a sink once, ruined the whole subfloor before we even noticed.
