Hi Tony. On second thoughts, you are probably better off leaving the ccv for a pro. They are infinitely reliable anyway and simply concentrate on ensuring the air filter isn't restricted in any way. If it is restricted, the vacuum from the intake will suck a small amount of oil from inside the engine
. If your air filter is good then I would seek proffessional advice. You would definitely notice an oil leak
of that volume so it is most likely an internal problem. BTW, does the engine
have high hours on it? Regards, Mick.
