The engine is dismantled now and it is obviously in much worse shape than thought before. It will need a complete overhaul 🙁
Just some highlights:

• the timing belt slipped by a few teeth, just too few to blow up the engine, but enough for some valves to hit the pistons
• the sprocket driving the oil pump got loose and damaged the crankshaft
• piston rings to be replaced
• all injection nozzles and glow plugs have to be replaced – OK, that at least was obvious from the beginning

I still hope we can join the first test race end of May…
This is how the engine looks like today:
