Hello, I am currently working on a Seat Ibiza 6L 1.4 TDI and am at the end with my knowledge. Now to the beginning of the whole: The Seat had a strong water loss of about 1 liter per day and misted accordingly strongly. After about 2 days of standstill the engine did not start and cared only. After a long organ he then jumped on and sounded strongly climpering/grinding. The first thought was that he had started to rust slightly during the service life, especially on the cylinder. I degraded the cylinder head and tested it for rust. Between cylinders 2 and 3 the cylinder head seal was damaged, and the cylinders had superficial rust. I then sanded it slightly with felt (if you can already call it grinding). Then the cylinder head seal and the extension screws were renewed and everything was put back on OT. Now everything is assembled again, but he orgles and still doesn’t start. Once he started, however, after approx. That means there is the same starting problem as in the beginning.
