Hi folks!

The IM shows that there are two connecting points available for the oil return hose to the oil tank at the bottom of the crankcase housing. Depending on the type of setup (puller or pusher) either or is to be used for best supply of oil within the circuit.

Is there anyone around with practical experience and knowledge what to expect when the "wrong" connection (other than pointed out in the IM) is used. OK, we won't get the "best supply", it'd be "less than optimum" but how does that show or materialize? Aspects like early aging of oil, oil temps in general or in specific phases of flight, engine wear and more spring to mind. 

Curious for hands on information!

    Is he engine level length wise? On the ground or in flight, pick the lowest point to get all oil returned to tank.

    Yes, let's assume that the engine is level on ground and during cruise. A little down pitch may be within the mount. However,  I'd think that it won't be an issue. During steep climbs with high power setting the wrong (too high) connection may be a bad choice (which I regard the basis for the recommendation in the IM).

    But are we talking about something "less than best" or "killing the engine". Would the wrong choice result in higher temps or get the oil to its operational limits?

    Has anyone performed a change from front to back position of that connection or vice versa. Where there any particular findings resulting from the switch?

    I'd use the one that's on the lowest end during a climb to keep the oil tank fed.
