Crankcase breather catch cans

Can you pull the tank filter and verify that both of the ports are free to go into the can? Some setups have a dip tube off one of the ports to be used as either open or closed system types…if you happen to get enough oil in there and the dip tube gets covered you’ll only be using the open port. Draining often enough can mitigate the “concern” (it’s not much of one, just worth noting).

Otherwise, just one tube 10AN or larger from each valve cover will make that a nice open system. Putting it lower promotes oil draining down to it rather than pooling in a belly, or draining back to the engine which you don’t want either since a decent portion of the mix is also fuel vapor…helps keep the oil a touch cleaner.

Also, what brand valve covers are those? And did they come with the bungs in them? I like em!
