Hi there I have a evo 6 rally car and currently chasing a misfire, comes under boost and obviously a lot worse with anti lag running, plugs and coils have been changed, I don't have a diag port too plug in due too being on a aftermarket management system the thing I did notice I took the cam position sensor off and the housing was full of oil is this normal? As when we cleaned this off it seemed too sort it but after a mile we checked it again and it was full of oil again? We're all out of ideas
cheers
