I think my engine may have siezed. I had a loud scraping noise that grew worse and then as I slowed down to make a turn the truck stalled. I pulled over and decided to let it cool down somewhat. Checked my oil and found nothing on the dipstick...yikes! Coolant was fine. Used my cell and had some oil brought to me. Started up the truck and travelled about 1/4 mile before it stalled again with bad scraping noise coming from the engine (before it stalled). (This was probably very foolish on my part) Had it towed home on a flatbed. Tried to start it to pull it in my driveway-just a clunk from the starter. I know it's early but does anybody have any advice or thoughts? I replaced the cylinder heads last year. Might I be able to save them (would they be damaged?) and will I be able to rebuild the bottom end or find a new/rebuilt bottom end somewhere and swap it out? <img src="/forums/images/graemlins/barf.gif" alt="" />
