I just purchased a valley cover from a forum member and there is no Vacuum port on it?

I'm switching from an ls6 to and LS2 and I knew I needed a different cover.....but don't I need the port?

Looks like it can easily be drilled/tapped and added, but then I don't have all that fancy PVC plastic apparatus that goes in the valley to keep oil out.

So did I get the wrong cover? Or what are my options?

Thanks!

You don't need it as long as you vent the engine properly through the valve covers.

LS2 Corvette valley covers all have the vent tube with a built in orifice type pcv valve built into the tube.

ok.......?

So what cars came with the cover I have that had no vent tube on the valley cover?

I'm guessing that it might be a Caddy.

It is true that LS2 covers come with the pvc. I was just saying that you don't need it. I previously had an eforce supercharger on my LS2 and that kit comes with a valley plate without it. Its no issue at all.

It is an LS6 caddy, getting an LS2 406 installed. Collecting parts currently, and got a valley cover with out a vent so I was curious for what I should do.

That is good news, I appreciate it.

Any pictures showing how you have the crank case ventilated or do you still use a pcv?

I'm curious how I should run mine. It is NA for now and mainly a street car with the occasional track day.
