Hi, I was driving my 240 with a SR and all of a sudden, there was this loud ticking noise. And when i would let go of the gas and the idle dropped, it dropped low enough for the engine to die. So I pulled into a parking lot, the engine was idling really low. I was looking under the hood to see if I noticed anything. And I saw that my engine was leaking oil from the bottom by the oil pan. I was able to drive it home, but it was driving like crap, the ticking was really loud. It died a couple of times on the way when i would let go of the gas. Today I checked my car out, I changed the oil to see if it was still leaking. And it's not leaking. I think it might be the oil pump. Help me somebody.
