Oil Breather ports on Oil Filler

[505-73Thing]

Where do these two ports connect if you have dual carbs? Just picked up a 70 ghia and the pictures are how they are set up now. The top port has a small air filter on it. Looking at various posts looks like some folks do this (air filter) and others connect to one of the carbs. Looks like a big debate.

The bottom one goes out the engine tin and is not capped or anything. That one I cannot find much discussion on. Mine just empties in the road. Should that be capped?

I'll post some pics.[/img]

the top vent on the oil filler should go either to the top of an air cleaner or to a breather you might mount on the firewall. Both these are good for a mild engine.
for a more race engine, you could use a bigger and better breather to seperate out the oil from the fumes and still direct to the air cleaner. eg:

or a bigger/better firewall breather eg:

the bottom vent under the car should have a rubber teat on it that clips into the small hole on the side, this:

good luck with sorting the engine breathing out
