Made a catch can by using an oil filter adapter with 4 ports 2 in and 2 out ran both driver side and passenger side vent hoses from the valve covers to the adapter with the arrows pointing out on the adapter and only use the big hose/fitting for vacuum from the air intake and capped the small vacuum fitting that went to the passenger side vent on the valve cover. You must remove the rubber seal/grommet from the oil filter its inside under the threads of the oil filter this will allow free vacuum unrestricted flow in both directions, I used a small pick and needle nose pliers to remove the seal. Made a bracket to secure the filter to the inner fender wall with a radiator clamp to secure the filter to the bracket. See pictures.
