the newest engine (2015) was due for its first oil change and I thought I would fit the quick oil change drain which I have on the other aircraft.

it makes oil changes quick and clean and I have been using them for over 13 years on Rotax engines.
however, on the new engines the partition plate in the base of the oil tank is dished (domed) with the dome facing the bottom of the tank. This prevents the oil drain being raised and locked in the open position to allow the oil to drain free.
I'm pretty sure my other engine (2004) has a flat plate as the bottom partition and therefore does not impede the drain.
other than making an adapter which will give the clearance required, I wondered what others who have faced the same problem , have done.
