Seems I might have a "new" problemette with my Vectra. I'm getting the same symptoms as in failed leak off pipes i.e. after several days being stood unused the car is very hard to start, just like the fuel system needs priming with fuel, exactly the same as the leak-off pipes failing. Thing is, the leak off pipes were changed recently (I will re-check them though). Garage (dealer) is suggesting that "seals have failed in the injectors" and a bill of circa £150 would follow from their repair. Suggestions? Is this a possibility? There was no oil in the leak-off pipes when they were changed. Dave
