Question about fuel injectors now...

K, got the motor back from the machine shop finally, built it back together, dropped it in the car. botled it in, BUT my fuel injectors dont sit in the intake manifold sterdy.... like.. there all connected to the fuel rail right i think. but there like bareeelllyyy even touching the hole in the manifold were there suppose to seat i believe. My question is are they suppose to be that loosely in there, or is there a gromet or something im missing that connects the injector ot its seat? Im thinkin they should be in there tight because otherwise boost pressure would just leak out, but i jut cant figure this out.:banghead: And what bugs me the most is ive had the fuel rail off before and everything went back together perfectly but that was a good 6-7 months ago so i cant remember exact what goes on with this... Anyways, any suggestions help.
Thanks again

you are definitley missing lower injector seals.
They are like little black donuts. They get plasticy over time and are often a spot for boost leaks. dealer will cost 8 bucks to get 4.
