I know the oil leaks when I went under the car to changed my oil for every 3k miles.. the oil leaks under the engines...and I am trying to understand where are the main sources oil can be leaking out of? can you explain where the sources of oil leaks? i have had replaced O-Ring (distrubotor) and gasket (top) where spart plugs go in.... right now, I am trying to understand where the oil engines go into the engines? my car 1996 Toyota Camry with 108700 miles, and the car has not given me any problems... I would appreciate if someone explains where the engine oil can be leaks?
