oil leak at engine
They have some head gasket problems (oil leaks).The most common leak is the upper and lower timing cover. Everytime I do one I use the silicone used in the ford recall campaign. It is a gray silicone made by permatex I believe . I do this on all 103 and 104 engines. They usually last for at least 5-6 years with no leak. There is no gasket between both timing covers and the block. The only rubber seal is between the upper timing cover and lower.
