PCV setup on carbed LSx

Been researching this today and I think I have some useful info.

The Gen III engine can use the LS6 valley plate which has a built-in PCV .

The later engines can use the LS3 valley plate.

The front pipe has a restrictive orifice and it should be plumbed to the intake behind the carb.

Guys at LS1tech have been doing this and also installing small filters on each valve cover that allow air to enter (not exit) each valve cover.

I also have a swap manual written by Joseph Potak that had instructions from GM crate engines that I have attached. These instructions seemed to contradict what others are doing : the driver side rear valve cover has a restricted tube that should also be connected to the intake.
Whether or not this is done doesn't seem to matter as the guys at LS1tech report no oil burning issues.

Hope this helps

No valley cover vent/port here

I had both valve covers Tee'd into the intake with a stock oil cap....first blast down the 1320' blew out the dip stick and sprayed oil everywhere.

I now have a filter where the cap goes, and both valve covers tied into an oil/air separator...no line back to the intake...NO issues
