On Friday evening the call came from a driver “I’m about to drive the engine under me” -loss of power (drastic) -noise like a big tank – restless and queish engine run (no error in the display statement immediately turn off engine, since we came with 2 SZM to the defects from the defective the cardan shaft unscrewed and dragged to us to the yard. There we took down the valve covers and found on the 2 cylinder no valve play!!!! and see, the piston of the 2nd cylinder has melted completely!! and was a smooth surface, what the cylinder head looks like I don’t need to describe or???? Then, with all the other 5 cylinders large inrun marks, shouted in the sockets, there is no cross cut anymore!! What can this come from??? Greeting
