Ok guys as the title states I have a 02 WS6 with fast intake and ls6 pcv conversion. Now my question is if I run a catch can do I need a valve cover breather or no for these aluminum valve covers?

Nobody running aluminum valve covers, tought this would be simple. Any opinions.. Im thinking maybe no breather on them remember I have LS6 pcv conversion in valley pan already just adding aluminim valve covers with a catch can.

ANYONE running an LS has aluminum valve covers. ALL LS valve covers are aluminum! You REALLY don't know what you are working with do you???

You should also know that you don't run breathers AND a PCV. It's either one or the other. If you're running breathers with the PCV still connected to the intake you're effectively pulling in unmetered air.

Take a look at this thread for general PCV routing methods.

Ok yea thats what I was thinking and I meant aftermarket tall aluminum valve covers not factory.

From the looks of those will I have to tap my valve covers for hoses??? Last image ls6 pcv with catch can.

I'm assuming your valve covers have an oil fill cap. If so, that can be drilled and tapped for a fresh air inlet a little easier than the cover itself.

Yes they do on pasenger side so route like this would be good.

What if you run a 4150 style throttle body,what would you do with the clean air side?

If you run speed density you can run a breather and PCV. The breather is the "clean" air side and the PCV still acts as the dirty side.

Thanks. That is what I need I need to do. I am in Speed Density. I will put a small breather on the clean side. I do not have that style valley cover that is in the diagram.
