I finally got the PCV system finished up.
My 90* elbows came in from Edelbrock - I had to order them through Summit Racing and it ended up being a custom order.
These 90's snap right into the LS9 valve covers - and cleans up the PCV hose routing a lot.
Also - after adding the catch can I went on a 30 mile drive. I got home and filled up the can.
I added a PCV valve between the drivers rear port and the can. I went on the same drive - and there was barely anything inside the catch can.
So I think I got the oiling issue resolved.
As for the half mile event this weekend - I've done a bunch of work on the truck to get it ready to tow the Vette up to VA.
I added a trailer brake, discovered that the rear U joint was cracked - so had that replaced and the DS rebalanced, replaced the the transfer case fluid, and got an alignment and ended up having to replace one of the batteries. So after all this work - i should be good to go.
