If it dropped a valve the seat or some other material could have gone through the Turbo and possibly damaged the Turbine wheel????

When it dropped the valve nothing other than the valve was damaged, engine still ran. Guide and seat where just fine. Polished the piston and installed a new valve and keepers. The ehaust wheel looks perfect
