I recently bought a Honda Civic 1976 and I was told that the previous owner that the engine was changed with an exported engine 80's and didn't specify and so I don't know the year or the model, and when I wanted to change the front valve cover gasket as it was leaking I was unable to find it in Egypt by all means as all I heard was this is an exported engine and we don't have the gasket and the avalibe ones don't line up correctly so the cover is still leaking, I'm unable to find any writing on the cover to lead me to the correct model in order to make an order online and by the correct gasket, attached some photos of the engine hoping that someone could lead me to the right direction so I can order the gasket online or even tell me how to identify the engine, please help.
