The common problems on the vauxhall engine are the leak off pipes or the leak Off seals on top of the injectors. disconnect the leak off return pipe and use a hand vac pump to check the leak off system holds a good vacuum. If it is the injector top seal you may see evidence of engine oil in the pipe.
If that's OK you will have to check pipe work and filter housing.
