What is this tube near the oil pressure switch?

[carolinawillys]

Anyone know what this tube is? There is nothing connected to it. It is a hollow tube with a rubber sleeve on the bottom. Thanks!

Never seen that before.

Here is a picture from above to see where the small end of the tube comes out.

Probably for emissions control.

What engine is that ?

Oil drip diverter from the airbox. The protruding tube connects to the bottom of the airbox with a length of hose. Connected, the oil drips on the heat exchanger, as is, it drips on the engine. Brilliant idea.

Maybe a catch can

The drain connection is on the bottom of your air cleaner.

I took that off of mine. I never get oil on the floor of my airbox.
