I went to replace my supercharger coupler the other day because i heard a rattling at idle so i go to remove the snout and find out that my coupler was fine and while removing the snout i ripped the supercharger gasket so off comes the charger. The supercharger wasn't even torqued down and it wasnt the orginial sc because there was junkyard marking on the bottom.It was trashed the impeller blades were rubbing against the housing and they were just toast. I ordered a rebuilt one off ebay and a new sc and tb gasket. I also ordered new injector o rings but i am waiting for the new charger to come in and i was wondering if there was anything else i could be doing besides cleaning? And also i removed my injectors and i need the little plastics pieces on the very bottom of the injector under the bottom o ring because some of mine r cracked and i have no idea where i could get them? Help would be greatly appreciated.
