Question I just remembered, maybe someone can help.

Chevy cheaped out on me and used same valve cover on both sides, each cover has an oil fill cap and a 15/16" hole. So I have a 15/16" port for the PCV that fits fine, but every breather I find is made to fit a 1 1/4" hole, I only have a 15/16" open port for the breather.

Does anyone know of a smaller breather or do I need to pull the cover and drill out the port?

Thanks
