RE: Europa-List: Oil temperature issue during climb

[Bud Yerly <budyerly@msn.com>]

Marcel,

If you have dropped your Mocal oil cooler supplied by Europa, as Ron said, 
ensure
you seal your duct bottom, and sides.
As you know the oil cooler is not as wide as the glycol cooler.  The gaps 
between
the metal duct and the fiberglass cowl must be closed or oil cooling is 
ineffective.
If you shine a light you should only see light coming through the fins.  No 
where
else.

Also, as a reminder, please check your oil temperature sender.  I use a 
separate thermocouple or infrared thermometer to verify the sender/gauge is 
working correctly.  You can swap the oil and cylinder sensors if you suspect 
the oil temp probe is not working.  See my troubleshooting manual on my website 
www.customflightcreations.com

If the ducting is tight, and the sender is good, you potentially have a supply
or return blockage.  If you have an oil thermostat in the line, it may be not
working properly or closed so the return line is blocked by the thermostat.  It
is possible to incorrectly hook up the oil lines creating a restricted flow.
Also check your oil tank vent line is clear and not holding pressure.

Personally, my 914 even in hot climates never runs over 250F degrees on a hard
climb.  Normally the glycol will climb to 245F (roughly boiling point in the 
heads)
well before the oil gets to the limit.

I hope you find the issue.

Best Regards,
Bud Yerly

Hi all,

I'm having some trouble with my oil temperature during climbing. The oil 
temperature
rises quite fast into yellow arc and would rise further without interrupt
the climbing phase. During horizontal flight everything is good.

I do have an Rotax 914, with the lowered oil radiator and a small lip at the 
outlet
behind the radiator. Last flight was below zero degrees and still a big issue.
I guess it all comes from the angle of attack, that gives turbulence's into
the main air channel.

Do you have any ideas how I could improve this issue?

How about removing the oil thermostat?

Many thanks

Marcel
