First shop job, we messed with pump timing. Now it's a crime. Feel weird about it now.

Back in my day, messing with pump timing was just part of figuring out how things work. I mean, it's not like you broke the engine on purpose, right? Sometimes you gotta tweak stuff to see what happens, and that's how you learn. Idk, maybe it's just me, but calling it a crime seems way over the top. We all made dumb moves when we were new, and it usually turns out fine. Hell, half the time those adjustments don't even cause real damage.

Honestly some of the best lessons come from screwing up. You adjust that timing, maybe blow a turbo seal, and suddenly you really get how the whole fuel system talks to the computer. @ryan_black is right about the fines, but sometimes you gotta see the black smoke yourself to learn why the book says don't do it. That weird feeling is just the cost of real world knowledge.

Used to side with @gray_white that messing with pump timing was just tinkering to learn. Then I saw a diesel rig spew so much black smoke it failed inspection. That simple tweak fried the injection system and the owner got a huge fine. Now I understand why it's a crime, because it wrecks expensive parts and pollutes badly. It's not just a dumb mistake anymore, it causes real world problems. So feeling weird about it now shows you've grown up.
