Want to find out what caused the catastrophic destruction of an OM 617 5 Cylinder turbo diesel engine? These engines are known for being indestructable so something really bad had to happen. Was it loss of oil, overheating, loss of timing chain, or some other major issue...or maybe it was something small that caused such a big expensive problem. Kent will show you the engine from a W126 300SD that literally came "unglued." He will walk you through his inspection process and show you some of the things he discovered when he examined the clylinder head, piston, and engine block.
