MY 97 E230 SEEMS TO HAVE BLOWN A HEAD GASKET. JUST DONE 138k . STARTED LOOSING WATER FROM EXPANSION TANK SLOWLY, OIL STILL OK AT THAT STAGE THEN WENT TO START ONE MORNING WITHOUT LUCK. APPARENTLY WATER IN CYLINDER i THINK ENGINEER WAS SAYING, HOWEVER WENT BACK 8 HOURS LATER AND IT STARTED STRAIGHT AWAY. CHECKED OIL AGAIN HAVING DONE AROUND 50 MILES AND 4 PINTS OF WATER AND LOOKS LIKE A MILKY COFFEE. MAIN STEALER WANTS £810 BEFORE ANY SKIMMING OR OTHER COMPLICATIONS. MB INDEPENDANT ARE TALKING UNDER £500
