oil fill tube

I have a 2009 polaris sportsman 800 EFI and I noticed some air blowing out of the oil fill tube, anyone know what causes this. Thanks

Assuming it was running while you pulledbthe dip stick.... this would be caused by the piston's motion. When running the bottom side if the engine works like an air pump so to speak, this is why the crank case is vented, to allow this air preasure to escape. If it is an over excessive amount of air you could have a little blow by and eventually a rebuild (new rings) will be in order. But some should be expected. I wouldn't recommend pulling the dip stick to check or add oil when running.

Thanks for your inpu, I have a 500 and it isnt blowing nearly like the 800, the 800 is not only blowing air but it seems loud vs the 500

Have to agree, don't open the fill cap with the engine running. If it has oil coming out with the engine off, then it's time for a new cap/dipstick.
