haha. ak, you have been a big help in my long thread as i have redoing the head gasket, machining the heads, lapping the valves, and lots of other stuff. Sorry if u r frustrated.
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.

Joe, thanks so much for this link. I ordered a set!

if the OP is interested in a new service kit for his originals -
this is a bit interesting. i'm thinking GM transitioned from bosch to rochester multecs sometime and during in 86 production run. curious to know if you have an iron head or an aluminum head L98?

It was an aluminum head L98 (it's now an L31-R with the aluminum heads and TPI on top, but that's another story)

There's no indication of when but SPO mentions (BOSCH) with "RP" LOGO for '85 1st design, some LUCAS in the mix '85 & '86 "CAV" LOGO and then another (BOSCH) "RP" LOGO for '86 and mentions 1st design. The LUCAS "CAV" mentions 2nd design. That always confused me.
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?
