I brought my vr-4 to the dealer to get my oil changed today since I was driving home for the break (don't have any tools at school to change the oil and I was about 100 miles overdue for an oil change)...seems simple enough, pretty hard to mess up on an oil change...drove about 160 miles home, as I hit the exit ramp, I noticed my oil pressure was extremely low (about 3 ticks driving) and as I put my clutch in, the oil light came on. I pulled over, immediately shut the car off, and called a tow truck. As I was waiting, I noticed a trail of oil, and looking under the car, i noticed a HUGE PUDDLE OF OIL UNDER THE ENGINE. I got the car home, and a couple of my friends helped me push the car up the driveway. I jacked it up, and noticed THE DAMN OIL DRAIN PLUG WAS MISSING!!!! I HAD NO ENGINE OIL!!! I'm pretty sure the plug was in place when I started my trip since I watched the oil gauge before I left...I suspect the plug fell off about 15 minutes before I pulled over (heard a little clanking sound, thought I just ran something over on the road). I'm going to call the dealership tomorrow and possibly a lawyer...I did take pictures, but its going to be hard to prove that it was the dealers fault (there's no scratches on the oil pan, so I didn't hit anything that would cause the plug to fall off). Anyways, what kind of damage can I expect have done to my engine? I did not notice any unusual noises (i.e. knock) when I shut off the engine, and I have not turned the car on since. Also, I was hoping anyone who had undergone a similar situation could give me advice on how to proceed? This is bullshit, I planned on having my oil changed before I left and was planning on changing it when I got home anyways, now I wish I didn't go to the dealer. Well, any help is appreciated.
