RESOLVED- ultrasonic injection cleaning/rich running

wotugonado · December 6, 2015, 15:05

Well in a pre emptive strike against mot emission failure that gives me sh!t every year, im looking at getting the injectors
sent off for the above treatment, has anyone on here done this and can recommend the company who did it ?

Id much rather use someone thats recommended to do the job than just pick a random company.

You can buy small ultrasonic baths easy enough, not sure what the routine for injectors are but I have used ultrasonics for years. If we have an expert on the matter here might be worth buying one. You need to determine what liquid is used in the cleaner as I wouldn't be too keen in using unleaded?

There are specific machines that do it - they flow test with Meths (I think?) and report back to make sure the injectors are flowing equally and within spec. TBH if the company have the correct machine I don't think there's much that can go wrong with it.

We bought an ultrasonic cleaner from Aldi some years ago. Works great on jewelry and stuff like that. Never had occasion to use it in injectors though.
I don't think the technology is quite as 'smoke and mirrors' as it's made out to be.

I would give somebody like ISL a ring and see what they say, at least you will get a ball park figure.

wotugonado · December 6, 2015, 22:05

Yeah I definitely want to send it off to be done properly, as I need the report to see if this is what's causing the issue. Theres a place on ebay doing them at £12.50 an injector, if no one recommends anywhere on here I might just use them and report back if theyre any good.

We use ultrasonic cleaning at work for Gas Turbine Aircraft engines, works well on carbon deposits etc and does not damage metal components, if the cleaning solution is left too long between changes it can stain parts but thats all. We use it on the Turbine blades, fuel atomisers and fuel/oil pipes etc, basically all the bits that get hot and dirty.

I can't remember your setup.
Mine has flown through 2 MOT in my ownership.
Turbo sports cat etc.

wotugonado · December 8, 2015, 20:55

Mines a Tte turbo, it did have a sports cat, but couldnt get through the mot with it on, failed emissions 3 times iirc. So i went through the whole turbo system found a leak fixed that (what a pita that was) put standard cat on and changed a lazy o2 sensor and it still only just scraped through the retest.
I have a problem with it running rich, so I hope an injector clean will help as im not sure what else it could be. Also while im thinking about it, i noticed the other day during gear change, foot comes off the accelerator but the engine continues to rev for a bit almost like its still getting fuel.

1979scotte · December 8, 2015, 21:13

Now that is strange.
With the OEM cat on should fly through easy.
If it was mine I'd blame the ecu and get the map looked at.
As yours is a TTE that can't be the issue.

Having had a turbo leak I feel your pain.

wotugonado · December 8, 2015, 21:43

Yep thats why im hoping an injector is leaking or faulty and a clean will sort it out or provide the answer.

Try Race-Tech Motorsport, in Sheffield. I think they charge £50 per set to check and clean.

Hi I may be missing the point here but I have used this additive every year before servicing and MOT and I've sailed through on emissions every time although that may be down to my MR2 being a 2006 model, I know its not snake oil because I feel the difference every time I use it and i've never felt like my car has lost HP since I bought it new in 2007 preregistered. the additive can be bought here and they are a very reliable company. One year they sent it in the post and it didn't arrive when estimated they sent out a replacement asap. It has got to be better than removing and cleaning injectors if it works. I also got some for my daughter in laws ailing 12 year old Fiesta that had injector/fuel delivery problems and it worked a treat. I think there are at least one other member who has tried it and reported it as positive. Go too m http://www.powerenhancer.co.uk/shop-by- ... 325ml.html m

If you use it put it in when you expect to be doing short regular trips rather than a long drive where you empty the tank as the longer it is in the system the better, One can is more than enough but I put it all in with a full tank and thats fine, because the ratio is greater than stated you can if you want fill up the tank again when 1/3 empty and it will still be an adequate dose, but effectively means its in your system longer.

The main point missed would be the added tte turbo. A standard car shouldn't have any issue passing.

Hopefully the injectors will sweeten the mot result but with standard cat fitted there shouldn't be a problem now you have fixed the leak you had last year.

Fingers crossed for you.

wotugonado · December 10, 2015, 15:24

I think if I have a problem with my injectors its a leak, so just using an additive wont resolve it. These companies do a full test so will find out any problem with them. As a side note they recommend the injectors be cleaned every 50000 miles to keep them functioning properly so at 84000 miles mine are well in need of doing.

s12vea · December 10, 2015, 15:55

Be interesting to know the out come of the test.

wotugonado · December 10, 2015, 16:04

Most of them do a before and after report so once I get it done I will post up on here.

stavros58 · December 10, 2015, 22:49

I think I might has missed the point about the Turbo but at the same time if you clean a fuel system through annually you are likely to have less fuel related issues regardless of whether you have a turbo or not at least that seems logical to me. I had to laugh though the ultrasonic cleaners sold at Aldi I think are for denture cleaning I know this because my dad bought one, guess they have multiple uses hope he passes the MOT and has a smile as bright as my dads s:D

Application areas:
jewellery, spectacles, watertight watches, razor heads, dental prosthesis (without facing), nibs, rubber stamps, printer heads,
COG-WHEELS, VALVES, EMBLEMS, MACHINE PARTS, eating and cooking utensils, cd's and dvd's.
(Source, the instruction manual).

I would certainly have bunged an injector in there to see what happened but I never had the need. Did a good job on the jewellery which is what we bought it for.

wotugonado · February 10, 2016, 22:57

Right so the mot is rapidly approaching and I cant put this off any longer unfortunately.
Im ordering the release tool for the fuel line but need to know what fuse to remove to disable the pump. So can anyone tell me which one it is please ?

Anonymous · February 11, 2016, 08:34

No need to remove the rail, bolt the rail and give the injectors a little pull / wiggle.

I thought it wouldn't have enough movement still attached. I will give it a try. Any idea which fuse to pull to disable the pump, or doesnt that matter if I don't disconnect the rail from the fuel line

best to pull the relay in the box on the firewall above the gearbox

wotugonado · February 13, 2016, 12:21

Cheers Rich you were right, didnt need to disconnect the rail.
Got them out, but theres no rubber seal on the bottom, presume theyre still in the injector holes is this a problem ?

Anonymous · February 13, 2016, 12:45

No problem, gently fish them out they will be fine. They a large donut shape. They problem o rings that don't like to seal are they top ones. Little wd40 for lubricant when putting back together.

Cant even see them s:)

s:) suppose its mirror job to find them.

Looked the injectors over and on the nozzle end 3 out of the 4 have a varnish like stain on them, 2 stained heavily, one stained a little and the last one is perfectly clean.

could it be clean because its continually leaking s:?: :?: s:?:
