Fuel Injector Cleaning

That's wat i've found in my injector while cleaning'em one at a time
by hand in brake cleaner(don't fear they do it in garage before reinstall)

You can't belive how it rev nice now.
note:i've used injector cleaner less than a month ago!!!

nice!
injector cleaner doesnt work, and you just proved that yet again.
i die a little inside everytime someone pays $9 for an 8oz bottle of "SUPER OCTANE 110" or "+ 5mpg inj. cleaner". yea adding 8oz will really increase 20gals of 93 up to 110 octane.
but seriously though try running some sea foam in the vac line now. thats is something that actualy does work at cleaning up carbon in the upper intake.

Use rubber gloves at least - cancer ain't fun and games.

Seafoam been done recently trust me this engine is almost new now
a stock serie one can kik some ass oh yeah

How difficult of a job is removing the injectors?

It's not too bad. You need to disconnect the fuel lines, then five nuts holding the rail on.

And pull hard to remove injectors from rails don't fear(but don't forget to remove clip before).

1 think i will add, is before u putt the injectors is to spray around them with WD-40 or PB blaster to lube the o rings u dont want to tear one of them and be for you install them lube them very well. i lubed mine like 5 or 6 times before installing and they went in like well i wont say it cuz its perverted

On an engine this old, I'd probably just replace the o-rings when reinstalling the injectors.

So, after removing them do you let them soak? And then scrub them?

yea, $40 or something like that from the dealer.
i got some sitting in my garage for when I do my injector upgrade.

I'm getting ready to do this and this question was never answered??

I figure as bad as Silver Arrow #10 was maintained they probably used the cheapest gas they could get too, and even with good gas with 180,000 miles on it I'm sure the injectors are a mess.
I've already done the seafoam in all three places so I figured this would be a good time to clean the injectors?

I have to ask, $40 for just the "O" rings?
I just got Fel-Pro "O" rings from Advance for $3 for a package of four, $9 plus tax?!?

Fel Pro Fuel Injection O-Ring Set
Part Number: ES70599
I'm not positive they fit yet, going to do it tomorrow, but that is what they listed for it.

99Rivman,
Did the FelPro O-rings work.
I'm going to swap my injectors soon and would like to know if I have to go to the dealer for proper O-Rings or not.
Thanks

They will work.

Man I Should Probably do this Considereing I have 160k and they have never been cleaned or changed, at least the old lady I bought it form didnt beat on here it was babied to the miliage it has

digging up an old thread, but i am doing this soon and the question asked on page 1 is still unanswered. so i'll ask it again:
do you just let them soak and them spray them off with brake cleaner? what do you soak them in?

thanks,
Matthew

I soaked mine in pure injector cleaner. From the first post in this thread I got the impression that they were soaked in brake cleaner....

I am toying with the idea of starting my own injector cleaning service. It requires no certification that i know of,and the ASNU machine is automatic and very easy to use. the machine does all this

It might be a good way to make extra cash and knowing many in the auto world would be to my advantage. what yall think??

How much will it cost you to get something like that?

I'm not sure. So far i haven't been able to locate a price online.Ill call the distributor as soon as the hour rolls around.They are also available used. This is an area many shops don't get involved in? i cant understand why? could it be that chasing "other" problems is more rewarding? Beats the hell outa me..

My guess is because many online places can get great coverage by shipping the injectors around. Take that mrinjector.us site you referenced in other threads. Injectors are so small, it wouldn't be a problem for me to ship them mine from Canada. And the overall amount of work they do on each injector is great for only 16$ each.

very true. regarding mrinjector,he gave me an 1 extra of everything and on the o-rings a couple more. And $5 bucks from where i am is good. But I bet i could turn a profit servicing them. There are classes to take to teach you everything you need to know,but no certification that i can see.
