Ford Lehman Oil Pan Breather Tube

This is more of a "for my information" type question.

I understand the purpose of a valve cover breather on a gasoline engine, but I notice there is what appears to be a breather tube coming out of the upper side of the oil pan on my Ford Lehman 120.

It is capped with what looks like an old style fuel tank cap that has a rubber gasket that fits down into the breather tube to stop it up, so doesn't appear to actually let anything "breathe" via this tube. The tube is approx 1 inch in diameter. It's located just under the Alternator and I can't find a picture of it in the manual.

Just curious about its purpose if someone knows and and can help educate me.

(Forgot to take a picture while at the boat, but can do that tomorrow if needed)

Thanks in advance.
Brad
