Citroen Jumper timing belt failure
The timing belt broke during normal running in slow speed, second gear and in approximate 30 km/h. The car was 9 years old and 170000 km, the timing belt has never been replaced. Took the head apart and the damage was limited to 6 lifters, a cracked camshaft house and a warped camshaft. The reason there was no more damage is probably due to the straight valve-piston arrangement, so no bent valves.
