Hi all
I have just got my rebuilt (by yours truly) motor running but have discovered that the injectors are somehow leaky, by leaky I mean that the seals are allowing air (vacum leak) into the cylinders. I am wondering what can be done to fix this. I had the injectors serviced when I rebuilt the engine, which included new seals, what is the process of checking the fuel rail and determining the cause of this leak, My engine is a 3S-FE and there is small dowels in the fuel rail, what length should these be and the tightness of the bolts... PLEASE HELP thanks in advance
