I have read the GM info about connection the PCV port on the pass side valve cover to the intake between the MAF and the throttle body.
What about the port on the rear of the drivers side valve cover?
Some of the guys on the LS forum connect both together using a Tee and then connect it to the intake.
What have some of you guys done?

I plan to use the pass side cover as you stated. Everything I've read says that is sufficient. My 5.3 truck uses the driver side rear port only. However I don't know why you couldn't tee them together if you wanted.

Thanks Andy. For now I'll just connect the pass side.
I'm thinking about adding an oil catch can later.
Getting ready to fire it up tomorrow morning. All the fluids are in, no leaks.
The engine is primed with oil and ready to go.
