235 oil catch can

[wspringerjr]

I installed an oil catch can after replacing my road draft tube with a pcv valve. I was curious to see how much oil was entering the intake so I installed a catch can ( glass jar )to see how much oil was pulling into the intake. After 317 miles I measured 7 ounces of oil in the jar from mixed highway driving to interstate speeds of 65 - 70. Does this seem like a normal amount of oil for a pcv system? Engine is not worn maybe 2 years rebuilt.
