Spent 4 hours chasing a phantom tube leak in a heat exchanger

I had this exchanger that kept sweating at the bottom tube sheet, swapped gaskets twice and even torqued the bolts to spec but it still dripped. Turned out a tiny pinhole in a tube about 3 rows back was spraying steam onto the sheet, not a gasket issue at all. Anyone else ever waste half a shift on something that was totally obvious in hindsight?

Man, my buddy spent a whole shift on a rattling blower that was just a loose bolt.
