"hat" tip rim broken off injector?? pics inside





i did not send my injectors away. i tested them for leak and spray pattern and cleaned them. didnt notice the broken tip at the time.
i researched these tips and they serve as a protection for the tip. not much else. my new orings are nice and tight and i used a teeny bit of silicon (dielectric) grease on the rubber.
i put this one injector at cyl 1. we will see if it affects anything. doubt it based on the comparison.
also, im guessing the rim broke off when either I, or a previous owner, yanked the rail out.
my parts were all cleaned and etched with eagle1 aluminum cleaner and if that plastic ring was in there i have no cleue where it went.
anyway, we will see. if my problem with crap idle and hesitation persist, ill irder a new set of rebuilt injectors from john at fic.
note these are bosches, not multecs, as the 85 did not come with multecs (win!)
when i first bought thecar 18 months ago i put a new autozone one in. its now got some discolorization and coating because of the leaking headgasket at 7. im hitting it with a torch to try and clean it but if i cant get the scale off ill replace.

on an upgrade set from FIC (boschIII's), unless the OP has budget considerations here. since VikingTrad3r is from Canada, and since the US/Canadian dollar exchange rate presently sucks, i'd consider home servicing my originals.
if the OP is interested in a new service kit for his originals -

I have cleaned injectors in the past. fairly easy for the home shop - plenty of youtube videos showing the procedure.

BTW, I read that multec injectors manufactured after 1995 did not have the ethanol gas/coil issue.

The only reasonable thought was that "it was a mix" of vendors for both '85 & '86 with maybe the better performing in real life being considered the winner. An R & D project for the TPI. LOL
The same "mix" was also the same for F-bodies but of course the 305 got a lesser injector. I always thought 19lb vs. 22lb. Maybe?
