Is the wonky piece one of the white plastic mechanisms? With like a wheel or with a spring attached? If so or not it might be that u lost a spring that forces the wonky piece back into place when u eject. The ps3 taking in disc's is pretty easy it's getting them back or getting them to spin right that's hard. U have to make sure that everything is n the right place right position and coinciding with the other pieces when u put it back together they should all be in one position closed with no disc in but when u put it back together u have to open up everything as if it were taking a diac so everything falls into place correctly hope this helps

Oh also it could have been when u used the screwdriver to manually turn everything and eject the disc. Try that again but turn it the opposite direction of when u did it last then if that doesn't work try back the other way. But before u do either of those be sure that all pieces are where they're are supposed to be and to really know that u have to watch it work with the top off to really see. When u manually turned it that makes all the gears catch and that either lifts or lowers ur disc reader so one of ur parts is not doing what it's supposed to or its not correctly in place.
