Hello.
Have you changed the breather filter that sits on left side of the rocker cover.If this never been changed,then that might be your problem.also if your running an aftermarket oil seperator can lead to more oil usage due to poor designs.
Blocking the metering unit to breather system will help but make sure its not something serious like rings etc if you do.
Turbo play is fine,long as it minor play.even in and out small fraction.ive had in and out play for two years and works fine.
