I have been studying (PCV) positive crankcase ventilation systems for my 8.1L engine. With the installation of the new intake manifold, the factory PCV was eliminated. This was a good thing because the 8.1L PCV system is known to draw oil into the intake and consume a quart every 1000 to 2000 miles. With me using fuel injection and ECM the distributor hole in the rear of the intake is not being used. My plan is to use this hole to draw air from the crankcase using a vacuum port on the intake. The aftermarket valve covers will have a breather in each one of them for filtered air supply. There will be a oil catch can between the distributor hole and the intake vacuum. The only thing I have not figured out is I want some type of baffle at the distributor hole and PVC Valve. The more I have read on this subject the more important a good working PCV system is to me. It's not the environmental aspect i'am worried about, it's all the positive things a good system does for your engine.
1. Less knock sensor ping keeping your engine running better
2. Less pressure in crankcase eliminating oil leaks.
3. Less crud in crankcase extending the life of your engine.
4. No mess in your engine bay from oil leaks.
5. Less pollutants in our environment.
This is just some of the more important things.
Here's a link to the best PCV valve I could find on the net. It is fully adjustable and rebuildable. You should read the info on their site, some good stuff on there.

If you have anything to add please chime in. Also i'am looking for a good oil catch can if you have any recommendations. As this progresses I will post on my build thread the system I will be using with pictures.
