As always we are not fortune tellers, tell us if the engine engraves due to lack of oil or does not start it and the hoops were hit ???
If the hoops were hit, with a striated key from the engine steering wheel you can turn it very slowly, little by little to leave, change of oil, filter and voila, if you engraving you work is ready brother, you have to do the full engine, or you turn some metal or you split any metal inside, I hope for your silver it is for the above!
