Well, you got me thinking – and I found this – https://www.youtube.com/watch?v=Ap1AH-9UNjU
Interesting, Possibly it could have been to get the oil out so it doesn’t carbon up the valves, like this guy rants about? It is a gas engine, but same difference.

Hello all, I have a 1994 C&C 37/40+ with a Yanmar 3JH2E engine. Interestingly, in the breather vent line leading to the air filter, there is a fitting with a hole in it that pretty clearly was intentionally installed, and even looks factory fitted. You can see it here: Breather Vent Tube.jpg <https://www.dropbox.com/s/l56ojbgqbh7eya5/Breather%20Vent%20Tube.jpg?dl=0> That leads to the center of the air filter, and presuming a vacuum is created when the engine is running, would mean the engine could be sucking in unfiltered air through this small hole. Do any of you know what the purpose of this fitting is? It does not show up in the overhaul or parts manual for this motor. I am thinking of getting rid of it. Thoughts? Thank you!
