The $14 torque wrench from Harbor Freight saved my engine swap

Last month I was torquing down the head bolts on my 94 Civic in Austin and my fancy Snap-on kept clicking early. Got so frustrated I grabbed that cheap Pittsburgh one I bought on a whim in 2019 just to compare. Turns out my expensive tool was off by 8 ft-lbs the whole time, probably why I had a blown head gasket in the first place. Anyone else ever caught a big brand tool being way out of spec?

Did you actually get your Snap-on checked against a certified calibration standard, or are we just trusting the Harbor Freight torque wrench to be the one that's right? I've seen cheap torque wrenches be dead on out of the box, sure, but I've also seen them drift way worse than the pricey ones after a few hard years. Blaming an 8 ft-lb miss on the tool alone feels like a stretch when head gaskets blow for a dozen other reasons anyway. If the cheap one is off by 10 lbs the other direction next month, are you gonna swap back and call it a draw? At the end of the day, a torque wrench is a tool you gotta check now and then, not a one-time holy grail.
