Hot take: Rushing through a timing belt change cost me an engine

I was in a hurry last week, had a customer breathing down my neck. Figured I could skip double checking the timing marks because I've done it a hundred times. Got everything back together, started it up, and heard this awful clunking sound. Turns out I was off by one tooth on the cam gear. Valves met the pistons, and the engine was toast. Now I'm dealing with a pissed off customer and a big repair bill. Seriously, no matter how many times you've done it, verify the timing every time. It's a simple step that saves you from disaster.
