[QUOTE="Voltwings, post: 14626870, member: 155561"] You can have both. I'm always a fan of having a vacuum on the crankcase during Daily driving, but obviously when boosted you need some means of crankcase ventilation. The setup we've done on several cars is pretty simple: Driver side PCV fitting to one side of a vented can Passenger side PCV to the other side of a vented can T into the passenger side line and run it to a sealed can attach Intake manifold to the other side of the sealed can. Check valve is placed between the IM and can that will close when the IM sees positive pressure Check valve is placed between the passenger side PCV fitting and vented can oriented so that it will close under vacuum, and open in the event of crankcase pressure. I wish i was at home and could post a picture of this, but some will notice this is a sealed system, but has a vent on the drivers side. This will cause a slight vacuum leak, but that's also really your only means of getting fresh air into the crankcase, and it is easily noted and/or compensated for in the tune. Sometimes its not even enough to warrant adjusting the fuel trims. Obviously not the cheapest way, but certainly i feel its the best. [/QUOTE]
