Diaphragm of PCV valve is in very good condition (No crack,no broken) but don't know why oil going to turbo , any cause you know why pcv valve consuming oil?

My 2009 camry le v4 is burning too much oil like emptying every 500 miles. The car is running smooth and give good mpg if i top up the oil every 300 - 500 miles. Will replacing pcv valve fix this issue ?

[@Kevinb1821]

Doesn’t your pcv system burn off oil vapor no matter what? Ever since I got an oil catch can I pour out about an ounce or 2 of oil everytime I fill up. I lose about a quart of oil every 3000 miles and I think that’s where the oils going. Not through the cylinder piston rings.
