Another Post with High Oil Temps
1st time poster on this forum. :P
I purchased a Medway EclipseR912 (80HP) flexwing microlight from a friend. The engine has 350hrs logged and was built in 2002.
As I'm totally rebuilding the aircraft at the moment (It has sat for a few years and needs a good tidy-up) I therefore haven't flown it myself, I'm going on what he has told me:-
The engine runs normally in usual Irish weather with normal oil temps/ pressure, BUT as soon as the air temp warms up and a slightly larger passenger is in the back seat then the Oil temps creep up to 120degrees but the oil pressure doesn't change.
He was blaming the passenger from disrupting the airflow to the cooler as it sits on top of the gearbox (sort of makes sense as the temps are normal when flying solo or the passenger crouches forward), so he fitted a larger cooler which solved the issue but changed back to the original cooler due to the new one developing a leak after a few years.
He also changed oil temp sender and the gauge but the problem still persists.
I have spoken to numerous other EclipseR owners who don't have this issue so it seems that my engine is the issue.
Now that the aircraft is stripped and the engine removed I would like to get to the bottom of this issue once and for all as my friend was working on this since he bought the aircraft in 2004 - I think him fitting the larger cooler is only disguising the real issue since no other owners of the same machine have any problems with oil temps.
Any advice will be welcomed.
Thanks
Steve.
