BTW I don't know what heads you're using, but the early Darts had some oil drainback issues, maybe this helps GOOD LUCK!

There are a few threads covering this on the Corvette forum also...

In my case I think the motor is fine, rather these two things are just more of an issue with more displacement and LS designed venting.

I just tq'ed my rockers to 18 ft/lbs and forgotta about it... You have to seal them?
I have ETP 225 heads if that makes a difference...

Lots of info here - - I won't touch the oil brand as it is a pet research project of mine but you stated that you were running a breather. If you are running a breather then you should NOT be running the PCV.
We pull and port many manifolds and are astonished at the oil in the galley from the PCV - - I used to use about a qt every 1500 and now use NONE at all.
Try plugging up the pcv first and where is your breather - - should be on the oil fill for proper size to evacuate pressure.
Good luck!!

i was thinking custom valve covers, and run 2 breathers
I've got about 600 miles on my ls2 402 now. It's not smoking at all and I can't detect any oil usage. I'm using Rotella and added the can of GM anti-scuff stuff that SDPC provided. I'm changing th oil this weekend. I'm either going to use Rotella again or Valvoline Racing (not for street) oil. It also has ZDDP in it. SDPC recommended not running Synthetic for the first 10K miles.
I tee'd the valve cover vents together and run that to the air bridge. I'm running a breather off the valley pan. I still haven't determined the final configuration for venting. It will involve a catch can or two.
