Bad electrolytic capacitors generally manifest by having high ESR rather than low capacitance, so I suspect this effect is what you are seeing. From Nichicon''s manual (response of a good capacitor): ESR increase is as a result of the electrolyte drying out in the capacitor. The aluminum cans are sealed with a rubber bung at the bottom which is ...
safety
An overload or reverse voltage will cause the capacitor to heat up until the vent (usually hard rubber) pops and vents out smelly gases, maybe leaving a puddle of electrolyte by the vent. At this point the capacitor is already destroyed and not usable. The capacitors that go "BANG" and send their metal cans flying along with a cloud of stinky wax paper are the smaller …
