Oil leaking everywhere, ahhhh

Question because im to lazy to check myself. Wouldn't any seal in that area normally have a circlip or ring to prevent it popping out?

Often just pressed fit ... as with most sealed bearings ..

Maybe this is a silly thought, but if the CS seal has been pushed out is that possibly because the crankcase pressure is too high? As in vent blocked or worn piston rings...

We went there earlier.

My ride went there also but previous owner rigged a long breather line out the back that could inflate car tires.

Never seen that on a bike. Rarely seen it anywhere, usually just a light press fit.

As someone said, it's possible that high crankcase pressure may have popped it out, some seals have a thicker skin of rubber on the OD, (presumably in order to seal better in the case) and they're not as tight.

Would still need serious performance crippling issues to get the case pressure that high though. The breather hose would be blown off it's spiggot first. There is one on the rocker cover as well don't forget.
