Cleaning fuel injectors?

[barno68]

I have not had any luck finding a shop that can clean injectors that are not in the car. This engine had 60k on it prior to rebuild, so I think they are ok, but would like to have them cleaned to be sure and can't justify $250+ for a new set.

Anyone know a good way to clean them? Could they be stood up in a pan and have the tips soaked in solvent? Thanks.

I know sonic cleaners work, but generally it's good to flush them too. Sonic cleaners are easy to get, they're basically a jewelry cleaner, $20-40 at the department stores. I'm not sure on the solvent to use though, however for the flush it might be good to use the fuel injecor cleaners you see at autozones.

Have you actually used a sonic cleaner? I am assuming that the injector is nothing more then a high speed solinoid, but am concerned about imersing them in water, but maybe it would not harm it. I took a look at the injector and can see that there would be some areas missed with using cleaner on the tips and inlet, but suppose that is better than nothing.

My Shop can do that. We flow test them too.

you wouldnt submerge the whole thing, certainly not. The part that the sonic cleaner would get at is the tip of the injector, where the pintle is (if its a pintle type, where there are the little holes that can get clogged.

Thanks for the replies, I soaked the tips in fuel injector cleaner, replaced the o-rings and reinstalled.

Jeff, if this does not work out I may send them to ya, but then again I don't think I will have the car run ready for another year...

On the bright side, I did get 6AN fittings welded on the supply and return fuel rail lines yesterday
