control chain and guide 2,3dt frontera

tach! am new here and right away a question: drive a frontera 2,3td bj 95. before 2 weeks the control chain tensioner / steering chain etc. was broken.I noticed in time and the engine remained healthy. my workshop needed almost 2 weeks to get the parts(the tension rail is still missing) is the normal thing with opel that this harm occurs after 130000km? or am I the depp that gets the ball in the stadium to the head? at my mv6 I know all weak spots. the parts I live in Spain and opel spain says: the car is older than 10 years, so no longer in the list, so not your problem. the span rail now comes from Germany-only I don’t know when. where can you get such parts?I found everything in the net but nothing. gruss molvizar
