You need to identify the exact point where the oil is coming from, as in from between the stator cover and the crankcase, or from between the oil feed line ant the right engine cover.

The 4 most likely reasons that gaskets fail to seal are:
> The old gasket was not completely removed, or
> The cover (or whatever) was over tightened and the gasket has split around one of the bolt holes.
> The gasket is out of position.
> An inappropriate sealer was used (Silicon RTV causes more leaks than it fixes when used on gaskets like this.

Also, if either of the mating surfaces or the gasket were damaged during installation (gouged, cracked, cut) that could do it.
