Broken gti6, update/help?

Agree with Grant. You need to stop looking for a miracle and just strip it down. There is clearly something not right, it has f*ck all compression and certainly sounds like it could have made contact. The tolerances are so small with these engines, even if the belt only slipped, it most likely would do damage. The more it's turned over, the more damage you're likely to have to deal with.
