Vectra C 2.2 SRI Direct, RAC patrol man, highlights a fuel leak on one of the injectors (i think he said Number 2 - counting from the left).

couldn't be fixed from the roadside, so got a tow to the garage.

can anyone mech/tech head tell me what it will cost to replace 'maybe' a seal on the injector? or if its a big big problem? as i dont wont to be ripped off in these tuff times.

cheers all
