I recently have checked my cam belt on my astra GTE 16v and i found out that there was a slight grove worn into the belt
I know the person who had the car before me had it changed along with the water pump and the two pullies, as i watched him do it about a year ago
anyway i had the belt changed, then i checked it again a week later and the grove had come back, once again
i dont know if this is supposed to happen or not but it just seems a bit strange?
I took a closer look at the belt and the case and that and i found out that althougth there was nothing touching the belt, it looked as though the belt was running over the edge of the idaler pully
is this supposed to happen?
the reason why i ask is that it was set up properly on the cahange and then when the engine was running it looked like the belt had moved there by itself
Has anyone else had a problem like this, please dont tell me my bearings have gone?
