As I removed the transmission from my inline VW-powered Vanagon, it slipped
off the Jack and got caught on the coolant supply for the rear heater. In
an inline, that's a hose from the front of the head, with a right angle
Bend and shaped like a horn.  This hose was repaired over 4 yrs ago using
Rescue Tape.  The hose took the full weight of the head, it was hanging
there while I schooched-out from under and grabbed a big block of wood to
slip under it.  After that, the tape was STILL holding!  I have an
aftermarket replacement that I never used, as backup.
