Hi all,

I decided to tackled installing AEM fpr to fix running lean issue from running F22c with MY02 ECU and tapped the fuel rail for a gauge myself over the weekend, though I'm not mechanically inclined at all. The install went pretty well, there was some leakage but it's now all clean. However, I realized that I didn't clean out all the shavings well enough. I picked up all the pieces as good as I could through the hole that I drilled, but pretty sure there are still some left. Due to my stupidity, I started the car up anyways, and it seemed to be running fine.

My questions are:
What kind of damage could I possibly have done?
Any suggestions on how to go back and take out all the shavings? Or is it too late?

Any input is greatly appreciated!

 

I am guessing this is on an OEM fuel rail. If so, you could have clogged one of the ports, and possible some made it down your return line. Its hard to say for sure due to shavings could have been big, small and every size/shape in between.

I would have the injectors tested and start taking things apart for visual inspection. Good luck.

 

each injector has a filter on the top, and there is a filter under the fuel pressure regulator, so any shavings are going to remain in the fuel rail or at the top of the injectors. Not likely to cause any damage but the injectors will have some crap in the filter area. If it was my car I'd take the fuel rail and injectors apart and clean out anything you can visually see with your eyes, and reinstall.

 

^ thanks for chiming in. I didnt know about the filters above the injectors.

 

Next time use a magnet top get the shavings out.

 

The fuel rail is aluminum I thought.

 

Yes no magnet works on aluminum. Unfortunately there is no short cuts with this job its seems. Best thing to have done (since you will now need to do it anyway) is remove the entire rail and perform the tap, then blow all the shavings out with compressed air ideally, or flush out with fluids, then reinstall clean as a whistle. It’s not that big a deal to completely remove the rail and reinstall. Takes about 15min.

 

Many past Honda injectors used to have removable filters on the tops, but I don't think the S2000 injectors have those last time I checked they are built into the injectors. I'm sure an injector service company can remove them but I couldn't tell how it might be done.

You should be able to remove any big pieces of metal, and if there are some small bits that remain trapped they shouldn't do any harm, but I would pull the rail and injectors and give everything a good flush with brake cleaner or something similar. Like mentioned above pulling the rail doesn't take long, the leaky fuel and fumes is a bit of a pain though.

 

Could you vacuum the stuff out? and is there any benefit to cleaning these filters you speak of for regular maintenance?

 

That is correct. In my experience they will remove these factory injector screens and put in replaceable filters when they go through the cleaning process.
