W116 injector seals too small for injector nozzle holder
I am installing new injector seals and nozzle holders on my 1977 280 SE. All genuine Mercedes parts. I noticed that the seals do not fit tightly in to the holders. I have attached a picture of this. The old original seals seem to fit tightly in to the old holders. I worry that this can cause false air to get in to the system which ironically is what this exercise is supposed to prevent.
Has anyone changed seals/holders and noticed this? I think the seals/holders are the same on all gas engines.
