Salar's engine has been misbehaving, or so we thought. It would rev to cruising speed then drop back, then speed up by itself. Even the engineer I usually have great faith in did not come up with a solution, despite trying everything. As a last resort I posted a question on a web forum and a process of fault-finding was suggested - starting right back at the tank. Bingo, there was the problem - not in the engine at all.
Salar was once petrol-driven, and the tank still had the gauze petrol filter fitted. Diesel tanks don't have them, any dirt ends up in the pre-filter. Salar had hidden her dirt problem from us, with a nice blob of muck embedded in the feeder pipe. Lesson of the day - start fault-finding at the beginning of the process, not in the middle! That cost me about three months fishing time.
