Why is it always weird stuff that breaks?

[Bruce Parker (RIP)]

Maybe it's just me but when one of my vehicles craps out it's always something strange. Like the time a flexible fuel line weakened and sucked shut when driving but idled fine. Or a set of points disintegrating into graphite dust.

Latest example? My carrier was getting harder and harder to start. So new plugs, wires, checking connections, timing...the works. I take the coil off the top of the distributer and see a crack in the bottom of the condenser leaking green goo. Not sure what the goo is (I didn't lick it) and also not sure if the condenser failing caused the crack or the crack caused the condenser to fail. Either way, more cash out the door to Macs for a new one.
