How much play should there be around the bottom of the injector at the intake.I" had the injectors cleaned and have had them back for months and can't remember if they fit snug at the intake.The inlets at the fuel rail fit snuggly.This is a13b turbo.Thanks

 

play = vac leak

 

You should be able to rotate them but they will not move up and down unless you have forgotten to install the grommets or diffusers.
