Can he put a patch on the leaks He Hee

Collector-Emitter leakage... LOL
What he's got is a shorted transistor. That's got nothing to do with
leakage.

The transistor that heats up immediately is
bad (excessive C-E leakage).

The DVM test procedure is to use the diode
check function. Imagine a transistor as
two diodes back-to-back with the base being
the common element. Test from base to emitter,
and from base to collector. You should only
get a reading in one direction on each test
(when the base is above either of the other
elements), and it should be around 600 mV.
