hello again, another problem i am experiencing in oil leaks. i noticed a substantial (5") puddle of oil on the garage floor coming from the passengers side of the engine. i checked numerous threads, and most seem to be on the drivers side. i checked under the car without jacking it up to get a quick look and noticed that the oil filter was loose, so i tightened that up (is that common?) that seemed to help a bunch, but still notice a few little drops on the same side. before i really dive into it, can anyone point out any common areas that i should focus on? thanks again!!
