I had the same problem, it literally drained my oil in a matter of minutes, turns out that where the oil filter screws to the bracket that's bolted to the engine that 2 oil lines run out and to the radiator for cooling, between that bracket and the engine there is a rubber o ring to keep it from leaking, mine was so old that it developed a crack in it, so I bought a universal O ring kit for it and installed it in just minutes, I couldn't believe that, that tiny crack let out all that oil, here I thought my engine was wasted for good this time. I owe a dept of gratitude to the parts man who diagnosed it. Of course I bought it from them, that was b 4 I new anything about this app, now I'd get whatever I need from Ifixit if they happen to have what I need that is. P S I hope this helps you, good luck.
