Pre ignition maybe ? The prechamber is a hot spot in the cylinder, it is inadvisable to use propane on a IDI engine. Damage has been done for certain but the extent of the damage can't be determined until you open the engine.A couple of bent rods and/or cracked pistons is possible. Suggest you get another engine, OM606 or OM603 and build it the proper way, 7.5-8mm pump elements and a big turbo.
