Hello all, yesterday at my V70 D5 (AWD Bj 2006 km 104′ the tensioning roller broke, almost paced, the engine went out immediately. The car is now in the workshop, a first compression measurement was ok except for a cylinder (#4) with 20% less. Tomorrow a new timing belt is put on and tested again. Who has experience with this? Can I trust the engine, should it run again? What about the water pump, should I change it precautionly? Thank you for feedback!
