I have injectors for my turbo set up, just relized that 1 of the injectors is cracked around the the plastic injector port. Is This going to be a big problem or can I still use it. Injector itself is not damaged but only the little black plastic piece around the injector. Any help would be greatly appreciated

 

probably not, if I visualize it from your description, sounds to me like its the pintle protector.
