I had just thought how nice and reliable my old diesels are and was about to reach my home port after a 4 hr. trip from winter storage when it happened. Lost revs on SB engine and shortly after the alarm sounded. I was on the fly so no gauges. I quickly shut down the engine and went to check. [--word removed--], oil and metal pieces all over the engine room. During the trip I went down several times and checked the gauges and also took a look into the engine room, and all seemed fine. After limping to port a closer investigation showed that piston nr 6 seems to have disintegrated and there is a fist size hole in the side of the engine block. - Earlier this spring I watched a guy fitting exhaust temperature alarm, and wondered to myself if they are worthwile. - Well, now I know. - So, I need a TAMD 122 block or complete engine. The one to be replaced/repaired is a 1989 TAMD A/C with 458 hp. This type was in production a short time before the 480 hp version came. I am interested in finding a 122 C series block or a complete engine. I would also consider two engines if you have 480 hps for sale. - I'm grateful for any tip as to where I could find salvation, anywhere in Europe.
