Gert,
A friend had the same problem with his 914 installation. The line had
"carbonized" and was quite brittle.
As far as I remember, he replaced the oil lines with Teflon lines from
Aircraft Spruce.

Subject: Europa-List: Oil return hose / 914
Hi
I have had an quite unpleasant experience while doing my annual.
The last month or so I have noticed a ( - very week) smell of "hot oil"
sometimes during take of...... and funny-enough only during take of.
Could not localize the reason until now when-disassembling the different
parts under the cowling for the 100 hours/annual check.
It looks like the oil - return - hose have been more than hot under
the-asbestos - fire - sleeve, and therefore have changed to a kind of
"glasslike".
I am sure it would have collapsed within the next hours.
The oil - line have been-routed according to Rotax installation manual an
d
instructions from Europa - app. 90 degree to the stb. side and up
alongside the intake manifold to the top of the-oil-tank
The problem is on that piece of the hose that runs between the turbo unit
and the bottom of the engine.
You better put that oil-line on your check - list if you fly behind a 914'
...
FYI - I have never seen higher oil-temp's than 110C (app. 230F) according
to the log in my FlyDat.
Have other had-similar experiences?
Gert
