Honestly, I used to haul a huge toolbox for every diesel fix. Tbh, after struggling with space on a boat in rough water, I saw that a small, smart kit works better. Ngl, it totally shifted my approach.
I was at the shop yesterday and a customer's truck smelled like a fast food joint. Turns out he tried running it on used cooking oil without proper filtering, and now the injectors are completely clogged. Are more people trying this kind of thing, or is it just my area?
I kept leaving my torque wrench on the same setting for all jobs. I figured it was a smart way to save a few seconds. Then I snapped a bolt on a diesel pump housing. The piece vanished into the bell housing like a magic trick. Took me two hours to find it, felt like a total fool.
You could learn just by listening to him work. These days, with all the computers, that skill seems lost.
I was always getting my fuel and air lines mixed up in my home shop. Now I put colored tape on each hose end, and it saves me a ton of time. How do you keep your lines straight?
