hello guys, I'm just putting my fuel rail back on after doing my head gasket job and I'm cleaning up my injectors. One out of eight has a broken rim on the brown tip of the injector.
I did not have any fuel leaking not did i have pressure leakdown, but I was chasing down a rich condition. That led me to discovering a compromise head gasket at number seven.
has anybody else seen this? With this affect performance? Obviously the injectors are designed to have a rim around the tip.
thanks for your help, my plan this evening was to reinstall the fuel rail and I'm kind of stalled out now

It looks like the missing "Hat Brim" was used as an Oring support, or one side of the Oring Groove. If the Oring seals properly without it then not a big deal, otherwise it may be a source for a vacuum leak.
I personally would buy a single injector and replace it.

Why? Just buy the hat and be done with it. That or send it somewhere like RC Engineering or FIC to have them all cleaned and tested. Or if they are Multecs, get a rebuilt set and put these where they belong. The recycle bin.
How would I know can not see it from here maybe still in the hole.
I would buy a matched set from FIC
My money, if I were a betting man, is on the hat breaking off, falling into the runner and into the cylinder, melted and evaporated and in the atmosphere.
If they are Multecs, use them as for Target practice/
Even if it is Multec, old injectors can always use a rehab but that depends on if he wants to spend the money or not.
I wouldn't throw good money after bad. Multec injectors have coils that are cooled by the fuel. Ethanol eats at the coils. It is very difficult to get pure gas today without ethanol so unless you can do just that, you have to figure that you are getting gas and ethanol. So, why rehab an injector set that is that vulnerable? A rehab costs $22 X 8 or $176. For $190 you can get a reman set so why bother?

You know what you bring up is a valid point. I didn't even think about the vulnerability. I was just thinking if they were that old they could use it.

As they say, just because you could sleep with your sister doesn't make it a good idea. But if you are from one of the Hillbilly areas, it might not be so bad that the family tree runs straight. Less presents to buy at X'mas and your in-laws are her in-laws so less fighting.

My thought is to find out if it is Multec or not first. If it isn't, rehab since they probably could use a rehab. If it is, new set.

from the OP's pics, the injectors are first generation bosch, and a fairly good injector. I am not aware of any multec injector having a pintle cap. 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 -
"hat" tip rim broken off injector?? pics inside
