Mercedes-Benz V6 and V8 engines had timing chain problems caused by balance shaft and idler gear failures. Mercedes produced certain models with defective gears in their balance shafts (M272 engines) or with defective idle gears ( M273 engines). These faulty gears wear out prematurely, excessively, and without warning, causing the vehicle to malfunction, the ‘check engine light’ to remain illuminated, and the vehicle to misfire or stop driving. A lawsuit was filed against Mercedes- Benz, and you can read the details below. 1 Timing chain failures can cause catastrophic engine damage. Early signs of this problem are the check engine light and engine noise. If the timing chain fails, the pistons can hit the valves and cause severe damage to the engine. Engines with the balance shaft worn sprocket were Mercedes-Benz 350 models (Example: E350 C350 etc. ) that were equipped with the M272 engine. Mercedes-Benz engine is typically labeled as 450 models that have the V8 M273 engine had problems with worn guide idler gear. The parts themselves are not very expensive, but they are very costly to replace.

it is a chain I did not see any belts attached to the cams all that I know at this point is there are big chunks of metal in the oil filter and laying around the cam shaft sprockets it had to bend the valves if not puching holes in the pistons right?

after reading what Kelly wrote (and he spent some time writing all that) do you still want to mess with this defectively engineered Benz? If you do, when there is a world full of cars, then you need more help than can be supplied here-
