Hi Danny,
As I recall, we noticed a similar thing with our 912S, early on. We
noticed that our oil pump inlet 'suction' was too high and suspected
that the 90 deg bend in the molded inlet oil line was collapsing (this
is the line from the oil cooler to the oil pump inlet). We replaced the
bend in the oil line with a short aluminum elbow, which reduced our
suction at the oil pump inlet. As I recall, this also reduced the drop
in oil pressure at higher rpms. The bend I am talking about is the one
just a few inches (maybe 4 inches?) from the oil pump inlet.

Hi All,
Can some one tell me if its normal for the oil pressure to
drop when revving up the engine. After start up the pressure immediately
reaches 4.5 bar, but when I throttle up it drops to 2.5. Is this strange
/ normal ? With all the talk about Rotax not liking oil starvation its
a bit concerning .
Cheers Danny
