Switched from injector cleaning machines to doing it by hand on a 6.7 Powerstroke in Raleigh

I used to swear by those ultrasonic cleaning machines for injectors. Quick and easy. But after three sets came back with the same rough idle within 6 months, I started pulling them apart and cleaning the screens and orifices by hand with a small pick and brake cleaner. It takes twice as long but I haven't had a single return on that job since last April. Anyone else find the manual way holds up better on high-mileage engines?

Man, that's rough. I feel for you on those returns... nothing worse than seeing the same truck pull back in with the same problem after you thought you fixed it. I switched to hand cleaning for the exact same reason on high-mileage stuff. Those little screens and orifices get so clogged up with carbon that even the best machine can't blast them clean sometimes. It's more work for sure but the peace of mind is worth it when you know every passage is actually open. I bet a lot of guys are running machines that just aren't getting the job done on these older 6.7s.

Three sets came back in six months? That's wild. I'd have lost my mind after the second return. I've been running a cleaning machine for years on 6.7s and never had that many failures. But now I'm wondering if my machine is a ticking time bomb. What kind of machine were you using before? I'm real curious if it's a brand thing or just bad luck on those trucks.
