Trying to find the source of a little oil leak! Yes...I know It seems to develop mainly on the right side of the engine. I carried out an oil change and service recently and set the valve gaps. I renewed the cam cover gaskets at the time.. I've checked the torque on the heads and visually the gasket seal seems fine. Head gaskets also seem ok. The leak seems to come from under the tank down into the engine but as I say mainly on the rh side. I'll take the tank off next and check the breather ho
