So I finally got my 2004 WRX on track yesterday. Something I've been wanting to do since I bought it 3 years ago. I had just put new all-season z-rated tires, and new pads and rotors, so I figured it was time to have some fun. Check fluids ahead of time, and was a little more than a quart low, so I topped it off. Got out on track and it ran great. I did about 5 laps, and the new tires and breaks where doing awesome. Then on the 6th lap, I notice a the power going in and out on the straits, so I pulled it in. Stopped in the paddock and left it running while I opened the hood, and let it cool down. After about 15 min, I shut it down and stood around talking with my friends about the power problem. They told me that I was probably getting a little over boost and that it was probably fine. After about a half an hour I decided to fire it back up and give it another go. Upon start up I heard something that made my heart sink. I tapped on the throttle and there was the sound again. The undeniable sound of bad rod bearing. I tried to nurse it home, but seeing as I was 100 miles from home, it was futile. The knocking was constant and define when under load. I got it to the nearest town and had it towed the rest of the way home.
So what the hell happened here? The engine temp never got above normal. There was still oil in the pan after the 6 lap session. I have no CELs or other lights. I was driving it when I was on track, but I was also short shifting because I didn't want to over do it (missed on that one). Car has 156k on it, and has had all regular maintenance and been well taken care of.
Another question, what do you guys think I can get if I sell it in it's current state? Interior is in great shape, and there is only a minor scuff/scratch on the front bumper from where I kissed the corner of the garage when I fist go the car. The windshield is cracked (like every other car in Colorado).
Thanks for the input all!
