Some amount of smell isn't unheard of as the mixture of dirty blow-by and moisture sitting in the can makes a pretty acrid aroma. That being said, if it's overwhelming and smells like it's everywhere, check to make sure the catch can's ball valve isn't leaking and that the PCV connections are all fully seated. If you don't see anything there, take a look at the check valves and ensure that they're facing the correct direction and aren't clogged.
