700RMK -one cylinder filling up with oil?

[Steep&DeepRider]

Have my motor on my 07 Dragon RMK apart and noticed pto side of the case was full of oil? Is this a check- valve issue and how can I determine which oil line it is? Has anyone had this problem, how to fix?
Any help would be appreciated.

Thanks,

oil

Sounds like check valve issue. Attach a small piece of oil line to each fitting one at a time. Use a disposible syringe and push oil through them. Should take a little effort. If not then it's stuck open. You could try pushing some brake cleaner through it and see if it starts working.

?

If stuck open, are they hard to replace? I thought they screwed into the case but I do not see threads...

They may be the press fit type if you don't see threads

All press fit that I know of. Usually red loctite too.
