I'm battling with an oil leak from the front of the camshafts and so far I have
Changed the two main seals, twice
Changed the small O rings twice
Changed valve cover gasket once
Sealed under the front caps twice
Changed the half moon seals twice
Sealed under gasket/half moon seals

Now I'm thinking the steel spacer behind the cam wheel is either worn where the seal runs or is on the wrong way around, the taper is engine side, is this correct as the seal is only just running on it. I'm thinking the previous owner might have put it on back to front. Does anyone know please before I set fire to it?
