Please research before posting on a topic.

The RX oil breather has a check valve to only allow air out of the crankcase, not in. This helps with positive crankcase ventilation and decreases oil blow by.

If you got an oil breather off of eBay per say, that didn't have a check valve. Then yes you would be letting unmetered air into the crankcase.
