Cleaning injectors, 1JZ-GTE. Advice please.

[TTMX83]

I have 12 injectors. Yellow color. I want to choose a set of 6 out of these. I want to know if anyone has had any issues taking them to get cleaned before. I don't want them to come back leaking etc...

Thankyou, Brad.

I have had my 550's cleaned before I put them in. Haven't had any issues.

[TTMX83]

Thanks, I'm in country Victoria and was a bit worried about the equipment the guy here has.

all the guys i know that had there injectors cleaned it basically stuffed them.

i never had mine cleaned. so i am only going of friends experience

[TTMX83]

Shane, that's what I had heard, hence the thread. Would getting them tested for flow/leaks be safe?

Cheers Brad.

dont know mate, injectors are not my strong point.


i dont know if its was the guy doing the cleaning, ie his mehtod, or wether there may be a cauze in them that then locks the shit in them,

got my injectors cleaned and everythin last week, car idles so much better nowwas good thing had them done as they were flowing down a bit makes a big difference

Jorrs, can you at all provide details of the process, or did you just drop em off?

The guy here said there were different cleaning solvents, some harsh and some soft which could eat the insides of the injector somehow. Seeing as he had never come across these ones before I was reluctant to give them to him.

oh sorry mate, misread first post. I got mine flowed and tested but they came back good so no need to clean just new orings and good to go.

Not to say this could not be the case, but there would not be a market for injector cleaning if they were all ending up stuffed.

I have had good results with a set for a 3s-fe.

For $18 each give or take, i think its worth giving it a go and gaining your own experience.

[Jorrs]

yeh just dropped them of, got four done for 98 bucks, tested and cleaned, 2 were in pretty bad shape and now have improved economy and the idle is smooth as

good stuff...

hey jorrs where abouts did you get them done at?

and i assumed you pulled them out of the car?

[JustCallMeOrlando]

I got my first set of injectors cleaned, plan is to get my 7M ones cleaned before my Microleb goes on. Cost me $99 for 6, trade price.

i think it comes down to what solvents they use, how "vigorous" the ultrasonic bath is, and if they are being pulsed with fluid runnign thru them at the same time...

some places seem dodgy, others never have probs.... fidn one that is recommended by a few people and go with them

nah the car was in workshop gettin the headgasket retensioned so while it was there i got them to get injectors cleaned, they sent it away to a place they use in town who has a flow bench, and cos hes a good bloke he just charged me wat it cost him to do it, but yeh as i said im sorry i didnt do it earlier

Thanks for that. I was concerned about the procedure. I'll just get them flow tested and find the best 6.

I think the main issue with side feed injectors is the fact that not many shops have a flow machine to test them after they have been ultrasonicaly cleaned. In addition, they seem to be more difficult to clean then standard top feed injectors anyway so that only compounds the problem.

If you get then cleaned AND flowed there shouldn't an issue.

i'm not saying that cleaning per se is bad, just that sometimes the results are not so good, but some shops seem to always do well, so it's important to check up that they do a good job first

[Starfire]

Cleaning is worthwhile but unless you get them flow checked you have missed half the point.

If you have several to choose from select the ones that have the closest flow rates - this will give you the best results.
