I have an 06 GTO. It has 20k miles on it. A few weeks ago, I noticed a slight ticking coming from under the car. I thought it was an exsaust leak, so I figured no problem. I let a buddy hear it, and we checked the oil. We had to add 4 quarts of oil to get it to the full line on the dip stick. I figured that the noise would go away, since the motor had good power and everything. I am not one to baby it, but I do run it. I take the rpm's around the 4/12 to 5 mark at times. I'm not going to B.S anyone hear, I change the oil myself, but do slip and miss the 3k mile mark at times since I put more than 3k miles on a month, lol. Last night, I was coming down my road, andthe motor started rapping EXTREMELY bad, and I parked it. This morning, I drove it to mechanic's whick is a skip away from my house. as I was pulling in the parking lot, the rapping got worse, the car shut down and smoke started coming from the hood. when I tried to start it, it just cliks and dosnt even turn over. There wasnt any oil on the ground and the the engine still had plenty of oil. There was a small amount of metal shavings on the dipstick, almost a metalic look to the oil on the dipstick. I had it towed to the dealer this afternoon, and they're supposed to look into it tomorrow....supposed to anyway. I dont know what happend to it, and will GM cover it under warranrty? I'm suspecting they wont. And if they dont, can the dealer just fix what happend to it, so I dont have to shell out thousands of dollars for a motor? I had warranty work done on it a few months ago due to a tranny synchro failure. I dont know if they can just rebuild it, or what? If anyone knows of any salvage yards that have any, please let me know. I', just really lost for words and anyone's help would be appreciated.
