Got this idea from reading posts and solutions other members have found, while looking for my solution.

First I use just what was laying around.

Then I drilled out the pressure release ball and spring on the top of the oil filter mount. (Not the mount for my engine.)

Grabbed an oil filler neck with the large opening.

The breather can vent out the grill, or I could run hoses back to the carburetors

All done
One hose attached to the filler neck, the other attached to the oil cover box below the filler.
And I ended up using another fuel nipple to a different oil filler without the large opening, it was too large for the hose to attach.

I have traveled 2500 miles with this set up, the amount below is from a 500 to 600 mile trip! A lot of moisture.
99% water that didn’t go in my engine.[size=4]

That’s brilliant! Well done. It looks like it belongs there from the get go.

Great job thinking outside the box.

Good stuff! I like the combination of a creative solution to a problem, combined with using what you have around to get it done. Thanks for posting,

I was seriously doubting that breather's effectiveness, but it certainly seems to be working! Do I see head vents in there? I can't really tell from the pictures.

I'd love to install something to keep my engine bay clean. Right now it's a hot mess.

A few changes after I found venting into the engine compartment was creating a bit of a mess. So I move the vent outside the car, and yes it created a little bit of a mess out there. So I added a T and split the vent between outside and fed to one carburetor. The slight draw from the carburetor should’ve eliminate any excess moisture traveling out the vent creating a mess.
About 500 more miles added to the jar.

In the fourth picture I modified the T position for a little better flow.
