Just wanted to get some opinions on my Crankcase ventilation system. Is it overkill? I have seen a couple of diagrams using the Drivers side turbo intake only and using the crossover tube between the valve covers, but I think a dedicated system for each bank should suffice. The check valves are using viton valve and the stock ones will be drilled out. Using -6 AN SS hose line for the bling bling factor. Anybody try this setup yet? the only change I would make, is on the second picture and that is to drill and tap a new hole for the breather filter so that the vacuum is across the entire passenger side valve cover, capping the stock hole of course.
