Omega B – X25XE – Timing belts skipped despite correct voltage

Hi guys, have an extremely strange and tricky problem. I changed the timing belt with my Opel Omega b 2.5 V6. Everything worked perfectly and drove about 2000km and then turned off the car for a week. Wanted to move the car again and when I started it there were two ignitions and the car went out again (thought the key just wouldn’t have turned long enough as it could happen with old cars times that they went out again) at the two The engine turned completely without compression. Diagnosis was clear… gills skipped. (probably lay on hand, tension roller defective or a mistake on my side when changing) Belts looked at and as suspected he had skipped two teeth at the crankshaft ( camshaft markings were perfect but crankshaft was wrong) The strange thing is that the belt had a tension like from the picture book and all tension rollers are top. No teeth torn off Belts look t like new and as if nothing ever happened. Has anyone ever experienced something like this and has an idea what it might be about… my only guess is that something has blocked the camshaft drive and will check it out in the coming days. If anyone else has any ideas like to report. Greetings Tobi.
