Had a 2022 Freightliner Cascadia in the shop yesterday with a blocked DEF injector after only 8,000 miles on a tank of that 'premium' synthetic stuff. I mean, the customer paid extra for it thinking it was better, but it crystallized way faster than the standard bulk brand we usually recommend. Has anyone else seen these new formulas causing more frequent dosing system issues?
Had a 1994 Dodge with the 5.9L in the shop yesterday for a rough idle. Traced it all the way back to a cracked injection pump mounting flange, which I've never seen before on that engine. The owner drove it from Boise thinking it was just a fuel filter. Anyone else run into something like that on the old mechanical pumps?
Honestly, last week I worked on a diesel pickup with a loud turbo noise. Tbh, one mechanic friend says to just keep an eye on it, but another argues it needs fixing right away. Ngl, I've seen turbos hold up for ages and others fail fast. Where do you stand on letting turbo noise slide versus immediate action?
Back then, a random stop could mean learning a NEW trick from an old timer. These days, it's all apps and no handshake, which just feels COLD.
Always check the simple stuff before tearing into the injection pump, lol.
Any diesel techs have good stretches or routines? I can't keep popping ibuprofen like candy, lol.
I miss the old roar... But I guess the new engines are better for the air. Still, it feels like part of the neighborhood's character is gone.
As a diesel mechanic, I often lift heavy injectors and it really hurt my shoulders. Last month, I started doing shoulder rolls during my breaks. Now, the sharp pain is gone and I feel stronger. I can work on engines without wincing every time I reach up. It's a small change, but it improved my days a lot. What do you guys do to handle the physical toll of the job?
It takes forever to find simple error codes now.
Everyone says to keep family far away from your work to avoid drama. I let my retired dad hang out while I was diagnosing a persistent turbo lag issue. His old stories about mechanical fixes from decades ago actually sparked the solution. Now I think shutting out family wisdom is a missed opportunity, don't you?
You save five minutes now but guarantee a comeback for a blown gasket.
You learn more from an engine in the snow than a warm garage.
At social events, someone always asks about their truck's weird noise. I found that carrying a small notepad to jot down the issue helps. Then I can look it up later without derailing the conversation. It keeps things friendly and I avoid giving advice on the spot.
It was wrapped in newspaper and worked like a charm, haha.
