from my own experience with 4000 miles on the odometer..bent rods, thrown pistons, and a lot of other things that end in scraping the motor. In my case I had to go further and have the rear end and transmission serviced, new carpet and padding, new brakes, a couple new sensors...i think thats it. Ended up costing me (actually my insurance) just under 7 grand..and I still regret not searching for crate motors like the mach 1 from carcraft or whatever was available 9 months ago.
