Could not find anything on this specifically, is this type of catch can legal?


Especially since it would not do:

9.1.3.i. Oil catch tanks are permitted. All engine breathers or vapor recirculation lines, if disconnected, shall vent to a catch tank of one (1) quart minimum capacity. Such catch tanks shall not be mounted in the driver/passenger compartment. Original valve cover(s) may be modified to alter or to add breather/filler.
Thanks,

Derek
