Robinson mounts their oil coolers with rigid lines directly to the cooling
baffles/fan/scroll unit which in turn is mounted rigid to the engine. As far
as I remember there is no soft material anywhere in between, though there is
some delicate mounting of the oiler to do, so as not to put any torsion
and/or tension in the mounted cooler.
Generally this outlasts the 2200 hr TBO of the whole machine....

Bernie, My oil cooler hangs from the same mounting brackets as my
evaporator
cores. They are attached to the engine rather than the motor mount. I do
have a layer of 1/8" red rubber strip for some vibration reduction between
the brackets and the cores.
While I am now aware the convention is to mount the cores on a
non-vibrating
surface such as engine mount or firewall mine are mounted to the engine.
Hopefully since my lines run from the engine to the cores/oil cooler they
all vibrate together and in sync and not out of phase {:>)
.
I have a total of 300 hours runtime on this set up.
Early on as Rusty mentioned I did have the cores develop leaks because( I
believe) I had 90 deg fittings and heavy fittings and hose hanging off of
that 90 deg fitting. Since I have eliminated the 90 deg fitting and gone
to
a straight vertical fitting, I have had no problem.
FWIW
