needs a breather

have both hoses off the rocker covers form to one hose, put that hose in one side of the catch can, and have the other side plumb into the blowoff plumb back, or to an air filter

YES IT NEEDS A VENT AND IT NEEDS ONE NOW. you can do some serious damage to your engine by having the crankcase breathers completely blocked (which they are now). either add a vent to the can or as above tee those 2 lines into one and feed it to the tank and use the other 'hole' as a vent. put a filter on it though as under the crankcase can suck in air via the breathers under vacuum and you want that air filtered.
