This BMW E87 with the good old N47 BMW diesel engine, had been brought to us with the complain of engine noises. The customer was suspicious about timing chain stretching. We decided to take a look under the valve/rocker cover and see what is the condition of it. Let's see what we have found out (except of the completely failed crankshaft pulley :D)
Car spec:
BMW E87 1 Series N47D20 177 hp
