Well not sure what it is?? I went to I Boats and they say it sounds like a blocked vent.

I blew air thur it and it is clear.

I am thinking that you are close in saying the cover is fitting to lose? The seal just might be to worn around the cover?

I am wondering if I can get just a seal or have to buy a whole new part 24??

I have been so busy that I just said the heck with itfor now!! It does not leak oil, Just pushes the cover off and you may see a little oil, but nothing to speak of.
