Re: 502 BB Chevy Oil Use
I know some will say garbage but here's what I've seen with my 454HO. After initial breakin it blew smoke on startup like crazy. Was only running on 6 or 7 cylinders and would take 5 minutes to burn up all the oil in the cylinders and start running on all 8. This was consistent, every startup.
I swapped the valve covers that come with the engine for the short chrome covers from my 396, no more smoke and starts on all 8. Also moved PCV valve hookup from intake to carb. Oil consumption is way down as well. Still less than 1000 miles on engine, maybe the rings have seated more. All I know is the change was dramatic. Wouldn't cost much to test this yourself. Remove PCV valve and replace with breather.
