oil COnsumption until 1 qt low

A quart in 500 is a big issue.

You need to drain the oil, and add back what the oil pan calls for and then check the full mark.
You could be overfilling it.
Otherwise the ring seal is crap, or you have a seal/guide issue or its pulling oil past the intake gasket.

BTW, you need a PCV. There is no reason NOT to use one.
