1 of my injectors is sprayinggas all over the place, 1 of the 2screw ports used to hold the fuel rail to the manifold is cracked on 1 side and i cant fully tighten it. What can i do to stop it from spraying?

You may have to replace the rail/injector(s). Is the injector cracked, or is it just spraying from where the fuel rail connects to it?

5pointslow91

it sprays from where the injector goes down into the manifold

mattdel

so the screw hole in the manifold is cracked?

5pointslow91

yes, and it only screws so far, the fuel rails arent snug and it seems like the injector does want to go down into the manifold all the way either

5pointslow91

does not*

mattdel

it will go in, as long as the rubber o-ring is the correct size. try putting some wd-40 or something equivalent on the o-ring, and pushing down on the rail, above that injector. it should pop in. after that, 1 screw SHOULD be enough to hold most of them tight, but I wouldn't be surprised if a couple of them leaked.

If you are still using a stock intake, I HIGHLY suggest you just purchase a stock lower intake from ebay or something... any kind of "fix" that a shop will offer you, to take care of that screw-hole, isn't going to work on aluminum.
