WE VERIFIED THAT THE LEAKAGE IS OCCURING BY THE TWO BOLTS WHEN THE ENGINE IS STARTED. WE PUT THE CAR IN THE ELEVATOR AND IDENTIFIED THAT THE BOTH BOLTS WERE LOOSE, THE BOLTS WERE SPINNING JUST WITH THE FINGERS MOVEMENT. THE BIG PROBLEM IS THAT BEYOND THE VERY LOW TORQUE, THE BOLTS ARE WITH LACRE INK, THAT MEAN TO SAY THAT THE OPERATOR USED LACRE INK, WITHOUT FIXE THE BOLTS.
