don't have any pics, but Its the bottom oil line that runs into the reservoir, it is the one with the screen on it. Other than that i don't think there is another screen.
i had too also. i "cleaned" my screen today. i put quotation marks around cleaned, because it was already immaculate. i found 1 spec of a fabric type material in it, but now i feel more secure about my engine's proneness to blow up. It also made me change my oil, which had about 10 hours on it. thanks all![/b]
