I've replaced the CCV and looking at the design of it, it gets sucked closed if there is too much vacuum from the intake and. So if the CCV valve is working correctly this theory should not be an issue.
My new valve made no difference to my oil consumption.
I also tried the blanking off the intake pipe and routing the CCV to a catch canister, but oil consumption was just as bad....
I'm working on another idea that I've carried out on my car but its too early to see if oil consumption has been affected
