855 GLE Automat, 10V, EZ 11/1993, 165 TKm Hello experts, my hydro ́s are clacking longer and louder after the morning cold start. So far it took only a few hundred meters, now I have to drive approx. 5 KM, until the clacking stops. Did the last oil change before 250 KM times at a chain (witzer). Supposedly Liqui-Moly with man filter. Can it lie at the wrong oil filter?. OIL is 10 W 40 (I always drive) Thinner OIL drives the oil consumption strongly up. Who has ever had new hydros installed and what did it cost? Greetings Friedi
