Is this ultra sonic cleaner a good alternative to pro cleaning?

[Infinitiguy19]

I want to clean my injectors since I have 6 that are off the rail and another 8 on my car, But how can I clean them my self without sending them to deatchworks?

Is brake parts cleaner fine to use on injectors?

Say what?

Much better to send rails with injectors installed to Deatschwerks. Confirm operation and calibration.

[Infinitiguy19]

Yea I don't doubt them, but there are work arounds for us cheap folks.

We can remove the rails ourselves

Pressure test them with air like Mike (Goody94Q45) did

also if this is a good solution clean them with the sonic cleaner

then brake parts cleaner to shine them up.

But to be fair I never got a price on how much an entire rail or two costs to be cleaned and re assemlbe at deatchworks.

And the above post is fixed, sorry.

[maxnix]

Heath did the air test rig.

It's pretty cheap with Deatsch.

It's like the drain and refill believers - it's better than nothing, but not cheaper for the servicing of the component long term.

[Infinitiguy19]

Well I will cal deatchworks and get some prices.

But I think if you flush all the fluids and change all the filters once, then drain and refil from there you should be good.

Then flush the everthing again every 5 years.

Can we all agree on that?

Brian forgets that he performs regular drain and fills every time he fills up his gas tank then the engine consumes the fuel. Geez get real!

Bet he does drain/fills on his coolant too....not worth messing with block drains.

I've been thinking about your cleaning question since you asked about it in another thread a few days ago. An ultrasound jewelry cleaner like the one you posted came to mind but it really doesn't clean the path that the fuel travels since the injector will be closed.

Now if a person could substitute BG44K or Red Line Injector cleaner and connect the injector leads to a 12v battery so you could open and close the injector it would do a little better job at cleaning the injector's fuel path. The problem with this method is how do you know that they're cleaned? Have a fire extinguisher close if you decide to try this.

On second thought, for $13 per injector (2007 price) I think I'd just send them to DeatchWerks.

[Infinitiguy19]

I supose you can try brake parts cleaner and a BG power flush when they are reinstalled can do the trick.

But in the summer I will see if I can send ONE injector to deatchworks and I will clean one my self and see what results I get, But only a power balance can reval that and thats not the best ways I suppose to do it, Unless I send the injector that I clean in to detchworks for them to compare.

But I fell like I am going overboad with this idea because they are only $13 each to have them professionally done with a warenty.

Thats alot of money. IMO since i dont have much.I was thinking buying some injector cleaner and cleaning them like that and we're set.Not to steal how do we do the compression test on the rail and flush it i think it was?

Anyways i bet if we put all the Nico minds together we can come up with a DIY injector cleaning method.

[goody90q45]

Money's tight Berner and when we did the power balance test on your Q all the injectors checked out about the same. None were plugged and only the 2 were ohming out of range. Get her back together and pour a can of BG44K (or 2 bottles of Redline injector cleaner) in the first full tank of gas. Down the road when you get an extra $100 take it in to a shop for a professional BG injector flush.

[unknown007]

Okay will do.I ohm'd them again by the way all ohm'd 12-12.1 and one ohm'd 12.4-12.5

[goody90q45]

Is this all 8 injectors or just the seven? If all 8 are now ohming in range you've got to suspect you may have a bad injector harness or had heavy corrosion on #3 (or was it #4) injector pins. How did the injector pins look? Clean or green? Is the harness brittle? Have you done a continuity/resistance check on each lead from the 8 pin connector to the injector connector?

No I ohm'd 6 that were in that range and the other two were dead on was 35 or maybe 3.5 and the other one was like 16 i think.The connectors were all green so i'll be cleaning that and ohming them again once i install the rails back with the injectors.I need to know how to do the compression test on the rails.If it's not necessary then nevermind.

[goody90q45]

Leak check on the assembled rail is very necessary before reinstalling it. There's lots of threads with pics out there. I've got to get some sleep. 3am comes early.

[unknown007]

Yup i will search it on here thanks.

Nope, power flush coolant, hydraulic fluid in brake lines, and mechanically exchange ATF simultaneous fill and extract PS fluid. Cursory familiarity will reveal even fuel is moved under pressure with a pump. Differential is only gravity drain and fill on my cars! Pressure differential is your friend when evacuating and installing fluids!

Now in the depression, some loaded Model T vintage trucks did have a fuel tank above the engine that was gravity fed.

Amazing what people don't know about their own cars.

And move those injectors to accessible locations that don't require removing the plenum again!

Or you'll be sorry very soon.

[Q451990]

I saw something online about ultrasonically cleaning them with mineral spirits. I would think a pressurized rail flush is the way to go though. The dirt you're worried about is on the inside of the injector, which won't be reached by the ultrasonic cleaner anyhow. You might find some marginal gains by doing both, but without the pressurized flush and a way of opening the injectors you're not accomplishing much.

If im doing anything wrong when removing the plenum please come foward and tell me.Or better yet let's see pictures of you doing it.

I won't be sorry I'll love to remove the plenum over and over and over agian.

[Infinitiguy19]

Well brian is removing the plenum right now.

Here is the topic on testing the O-rings on the fuel injectors before installing the rail on the car: zerothread?id=366243

[unknown007]

Who's brian?

[Infinitiguy19]

I knew you would say that: Brian AKA Maxnix

[unknown007]

oh he's not taking anything off. Pics=proof well hope he's doing it perfect.since i cant.

[unknown007]

I found the answer to this problem!!!YAY!!!

Hey is this a good method for cleaning them:

Here's what you need to clean your injectors:

injector wiring pigtailspray carb cleanerjumber wires with alligator clips9V battery

Remove the injectors.Attach injector pigtail.Hook jumper wires to injector pigtail and 9V battery. Polarity doesn't matter. (9V battery raises pintel off seat)Spray carb cleaner through injector until you have a good spray pattern. Wear eye protection and any safety gear deemed appropriate!Repeat with the other 7 injectors.Reinstall.

It's that easy, it's low buck, you can DIY!

...members' standards vary...

not only is simultaneous drain/fill good for you automobile, it's also great for your bladder. good to always keep a jug full of water or pepsi next to your toilet... remind me to also post a youtube link of myself eating taco bell while sitting on the john
