GM 350 crate oil burner

For what it's worth , Do you have Aftermarket Valve covers?
Once I bought a 80 suburban with a 350. It had M/T valve covers and used 1 QT. oil
every 200 miles. I swapped them out for a pair of stock covers because I liked the look better. My oil use dropped to 1QT every 2800 miles!
Stock GM oil separators are that much better than a aftermarket tin shield.
All the Best, Dirk

Dirk is right on about the tin oil shield on some aftermarket valve covers including some by Edelbrock. GM didn't put the step baffles in the stock covers simply to get rid of some extra metal they had and if yours do not have step baffles you have most likely found the problem. Step baffles prevent the PCV valve from sucking the oil into the intake and depositing it on your intake valves in the form of carbon..
