RX-200 - Oil Seal Problem

[Hiskid1950]

My wife blew a belt last summer on the RX. She was moving pretty
fast so the belt got shredded up bad. One of the wires tore into the
oil seal and pushed it into the engine. I carefully extracted it so the
shaft would not be damaged. I cleaned/smoothed where the seal
seated. I put a new seal and it seemed to go so far then seat.
Problem is when the scoot starts running it pops right out and oil
starts leaking into the case. I got some permatex sealer that stays
flexible but it just popped right out also. I cleaned the shaft and the
seat area with alcohol. She just asked can I get it running for the
riding season so I figure I better hit the forum. Anyone ever run
into this problem? Is it possible to epoxy in ? Thanks GBY
