Need some input on venting the valve covers. I'm running a mp 70mm single turbo on a stock bottom end 01 ls1 speed inc tu1 cam with an 04 pcv set up. I changed out the factory valve covers for the Chevrolet ones and they have no provisions for venting. Only has oil fill. I plan on running 7-8 lbs of boost to keep the motor safe. Can I just run a hose from the valley cover to catch can and then to the manifold or do I need to add vents. Trying to avoid it If I can.

 

You could get one of those oil cap filters from speed inc or ebay. I had one and it's made a difference in crank pressure. I also haven't had an issue with any oil residue from the filter area. I also have a dual catch can setup.

I've got the same valve covers, but no FI .
You need a constant fresh source being pulled through the crank case.
Here's the easiest solution, that replaces your oil fill cap:

The best way would be to and some -AN fittings to each valve cover and run them both into a T fitting and then to your fresh airs source (tb, intake tube) . This way allows fresh air to flow through both banks of the engine, down through the crank case and back up and out through the valley cover.
With the easy first option the fresh air is only being pull through the passenger side valve cover no fresh air will be displacing crank case contaminants on the driver side of the block.
