JAMES dont be silly,
The fuel comes from a high pressure pump to the fuel rail which distributes the fuel to all injectors, the fuel rail then returns any unwanted fuel back to the tank, you cannot and must not block up any returns! the fuel rail and injectors have all been ultrasonic cleaned and tested for flow and pattern before the motor was put together to make sure that there were no problems with them, the fuel rail has a pressure gauge on it to monitor the pressure and its firm at 38psi which is on spec. I build once properly not twice badly (but thats a dream if it works first time). As far as a air leak is conceren i dont think there are any as it is all new but its worth trying with some oil spray. As for tight valves the liffters are hyd and i have checked them all, the other bank by the way did have a sticking valve after the rebuild but once it was re adjusted the problem stopped, i checked all compressions after and they are all fine.
