I heard you can clean this a few times before replacement? Has anyone done this and how?

under the CDRV is a wire mesh condenser in the valve cover. Take tha valvecover off and clean the mesh with carb cleaner to reduce oil through the turbo, as the cleaner it is the better it will do it's job.

Will the valve cover come off without removing the fuel injector lines?
