We need more PCV info apparently. If you do the line from the oil cap to the tb, isn't that just one half of the system? I've been looking at some of these elaborate bypass systems not just for a 3800 but other vehicles and it gets confusing. If I'm looking at these correctly there is the part of the system that drawns in air (I'm assuming this is the TB to oil cap part you mention), but isn't there another half where the gases are vented?

Granted I'm not too worried since no one yet has posted about any issues, other than the completely blocked PCV's. However I'm interested, if there is a real benefit and doesn't ugly up what already has become cluttered.
