I failed a smog test and the code was po456 which I have seen relates to an evaporative system leak. I just got an oul change and they said I had a slight oil leak. Could this be the cause for the po456 code? Also on the smog test the only ECS test that I failed was "System Malfunction Light" I would appreciate any input.

Could an oil leak be related to this?
