"This carb's" bowl vent tube is visible in the picture.

The epoxied in tube for crankcase vent is visible in the picture.

yes i see the carbs bowl vent... sorry for any confusion but im asking the OP why the hole in the air cleaner is expoxied as it looks to still be open. hard to tell in the posted pics.

& after looking closer at the pics, i realize turning the base wouldn't align the hole with the carb vent, but still curious why the hole in the base is epoxied like that.........................

Crank case vent goes between the filter and carb throat on open element breathers.

David's vent tube was added by him with epoxy

I think he just epoxied some type of nipple there for the valve cover vent to mate up to with a piece of rubber hose. Pretty much like the factory did it except underneath rather than on the side..since he doesn't have a 'side'.
Couldn't find a good Pontiac pic...

Vent line from the passenger valve cover. Breather on the driver side.
I failed JB Weld class......
I found a nearly flat base that still allows a 4" filter, so I no longer run this one. I added a nipple to the flatter one also.
