have oil leaking at rear of engine, collecting on top of tranny case, can't see from above, but apparently my camshaft sensor is going out as well because my "check engine" light is on and starting the engine is taking longer and longer (while cranking it). I had a technician check my codes and he told me the sensor is bad (or going bad, and eventually I won't be able to start the car...) so maybe this oil leak is coming from that? (it's collecting below that spot on the engine..)
