Aftermarket Valve Covers & PCV setup question
How do you have your PCV system setup?
I currently have this on raised stock valve covers:
Metco on oil fill hole
Catch can from passenger side valve cover to TB
Breather on driver's side valve cover where PCV valve used to be
I am thinking of switching to this setup with aftermarket valve covers:
Breather on Oil fill hole
Get LS6 valley cover
Catch can between valley cover and TB
What do you think would be the optimal setup? The car is not a daily driver, and is tuned in speed density.
Thanks,
Wes
If your car was tuned in speed density with your current breather setup, I would tread lightly when you make changes. If you are still allowing PCV flow into the intake and are running open breathers, the PCM is expecting a given amount of airflow. Since you don't have mass air, it has no way of knowing when you make a change other than O2 sensor readings and idle speed fluctuations.

So it seems as long as the system's not completely closed off, you should be fine?
Thanks guys.

Once my valve covers get here, we're going to see what this motor puts down. It sounds pretty mean with no mufflers.
