[HeyTeeee]

Hello again All! I ordered injectors before I did my VC (still waiting to get that shit show repaired) and I noticed that the cap is only over the tip, not over the tip + teflon seal. Nearly all the diy vids I’ve seen have the cap over the seal except an ABR houston one where they installed a new seal and compressed it with 3 different fittings. I’m wondering if the seals on these new injectors need to be compressed before install? I’m assuming they do which leaves me curious as to why they wouldn’t come compressed right outta the box.

N54 injectors come with the plastic covering the seal. The N55 injectors I have ordered do not. That plastic isn't there to "compress" the seal it's there to keep it from being damaged. You still need the injector tool to compress the Teflon. They do come semi-compressed though so you can probably pop them in without needing to compress them more. Just takes more effort and you risk putting a gouge in the seal. It's one of thos "will it work, yes, but is it the right way?" type things.

All my injectors that are Bosch made from FCP came with the white cap that covers the tip. EU5 however. Yours might not be EU5..

All I can comment is that I've replaced 4 injectors and just put them in. No special tool and no issues. I'm not even really sure how they would even be compressed since they are flush with the rest of the injector.

I too prefer to do things the right way. That is good info to know thank you!

I sure hope they are I ordered them based off of real oem and the build date of the car.

I did notice there are 2 part numbers listed 13537568607 & 13648625397, FCP said the newer number would fit ECS said it wouldn't so that's a little troubling. I ended up ordering 8607

You need to use ISTA-D/Rheingold or INPA to verify which EU version your injectors are. I'd assume most E-series should all be EU5 style (8607).

To add to this comment..

Only Latest ISTA has this function. Alot of ista versions are circulating out there that will not be able to run that check.

Late E series have a different version.

Well shit x) Looks like I found my task this weekend.

[HeyTeeee]

Not a big deal car isn't ready to swap injectors yet anyways but this is all good info thanks yall!

You sure you aren't thinking about INPA? ISTA-D can do everything. INPA can only do what scripts it's loaded with and most of the circulating copies are in German and/or aren't loaded with any of the useful scripts.

i am 100 % sure it even says on FCP site.

From site " vehicle using ISTAD 4.04 or later test plan using the following path"
That statement is true.

See you can program with older ISTA but you cannot check. That function is not built on older versions..
ISTA INPA completely different programs ..

good to know.

You can just look at your old injector too lol... much easier.

I have a 2011 135i, but I assume the engine is identical. If it's built before 1/1/2011 it requires bottom-mount injectors. Built after 1/1/2011 it uses top-mount injectors. FCPEuro doesn't take this build date difference into account so it'll show that both versions fit, but that's not true. RealOEM will list the correct part numbers for the respective build date. Another important note is that these two versions of injectors require DIFFERENT injector removal tools. FCPEuro doesn't even sell the correct tool for build dates prior to 1/1/2011. If you need more info on part numbers I can dig them up.

I didn't compress anything when I installed my injectors, but I did install using the injector removal tool according to the instructions on newtis.info. N55 injectors definitely aren't the same as N54 and if you do a search online for injector installation you'll only find N54... newtis.info was the only place I found with the correct info for N55.

yeah for sure but when i did it i was ordering parts before i pulled them so i dont get stuck without a car. Because with injectors as you know once removed u have to re teflon seal them

I’ve seen a couple tools out there. Anyone know if this Schwaben tool 023883SCH01A will work on the n55 injectors? It says n54...yet the baum kit B130190KIT which has from what I can tell from pics the same 3 pieces to compress the teflon seal and works for n54. I don’t mind cashing out for the correct tools as I prefer to do things right, but that’s a huge price difference for the same result if the Schwaben tool is compatible for n55

Eyeballing these injectors it’s pretty close to flush. If my eyeballs can see an edge I’d say that’s out of my risk tolerance for shoving injectors in. Maybe I’m being nitpicky? I’ll get a photo here in a few minutes

[HeyTeeee]

Best images I could get with an iphone and still in their sealed packaging. I could easily be thinking too cautiously so by all means feel free to correct me I want to learn, that's a huge gap imo and certainly not flush.

Thank you for your input! my build date is 9/2010. The holding bracket for my injectors are on the top, I observed this when I did the VC and took note of it. Come to think of it I don't think I've seen a video of using any tool to install the injectors they just shoved them in and called it a day?!

[HeyTeeee]

After quite a few searches and no real solid answers about the tool I ended up ordering this: http://www.freedomracing.com/130191-...r-kit-alt.html

Now I’ve peeked at others posts showing images of the o ring And they look pretty damn flush compared to mine. From anyone’s experience will it expand or should I be concerned with that gap? I also plan on coding them with Protool any tips? Looks pretty straightforward note the numbers do one at a time etc

When you order new injectors they come with teflon seals installed.. what are you going to use that tool for ?

It is basically the tool(s) used in my Bentley manual. A diy vid I watched use the three pieces to compress the seal before installing into the head, another video had a metal seal covering tip + seal. I didn’t want to take the chance of gouging the seal like another member stated earlier. Plus, if I or someone else needs to do something with injectors I’ve got the tools
