I would like to see a vacuum gauge put on a catch can system. If it sees any vacuum at all, it has be very small. So how much can it do over just venting???? Really. Lets get somebody with a vacuum gauge to do some RD.... gut feeling there is very little Vacuum, but I like to be surprised... I would suggest that a tap into the valley would be the best place... though I saw a fitting there last time my intake was off... last week. I vent and there is "some build-up" on my intake valves, I clean it up with nylon brush and some deposit remover...
