Docile 64 Report post Posted November 20, 2012 Ok so cousin's 318i e46 has a lot of oil in the radiator. car has been at the mechanics and said there is no water in the engine oil so probably its from the transmission. transmission specialist just called and said there is no water in the transmission to suggest a leak. anyone got an idea to what the problem might be?
