crank case ventilation.?
Have a twin turbo ls2 pushing around 14psi. I had a oil cap with a filter on top for the blowby, also two vent hoses on p/s valve cover, 1 vent hose on d/s valve cover and 1 vent hose on valley cover. I put a stock oil cap back on it due to the smell it allows in the cabin. Do y'all think without the vented oil cap there will be enough ventilation ?

I doubt it. Those holes on the valve cover are awfully small if they are the ones I think you are referring too. Most people are doing dual -10 or -12 to get the job done. I went cheap and did 3/4" hose off the DS cover and did the breather on the oil cap. I have very good ring seal though, and it takes forever to see traces of oil.
