Ultrasonic injector cleaning... when?

ronwest · 13-01-2010, 11:48 PM

My car is coming up to 170k and has never had the injectors cleaned.

I'm guessing they're due but does anyone know the recommended interval for (out of engine) cleaning?

Man personally ever 6 months inmho but not more than 12 months for peak performance. I take mine out and have a fuel pump submerged in cleaner then an external fuel rail ...i throe the injectors away and connect it to a spare 12 voly battery I have..works a treat

I chased this up a bit.

My local EFI place quoted $45ea + $90 labour (R/R) to ultrasonic clean = $360

I read this about cleaning vs new http://www.bosch.com.au/content/language1/html/4554.htm

and then came across this guy on ebay http://tinyurl.com/ykygztk

I contacted the ebay guy and postage is combined on a 6 buy so...

$49.50ea + $15 postage = $312 (DIY labour).

I'll buy the new ones

Just to add a bit more, I had a race engine builder through work yesterday and he was saying that unless there is a reason to suspect an injector problem (rough idle etc) he wouldn't worry about them until around 250K (on the family hack).

I think I'll replace mine anyway. It'll be peace of mind if nothing else.

I think its an over kill, but also quality of fuels and how often the car is operated would make a difference.

If car is operating frequesntly with good fuel than injectors get cleaned (the additives in the fuel and the pressure at the nozzle.

With carbys I find when they sit around alot the jets block up as fuel vapourizers and leaves a resedue.

i think like you Ronwest, i would rather do maintenance early than wait for the cruiser to fail, and you end up with some good spares.....good post by the way.

LOL! I first read that as "I think I like you ronwest"... I was trying to figure out how to let you down gently

Yeah, 90% of it's k's are on trips away so I like to keep on top of things. It's also a long time since I've had a car with more than 60Ks under the belt and even though I know it's no prob at 170Ks I like the peace of mind that prev mtce gives.

We're off to Palm Cove (Cairns) in April and then Perth in July/Aug and the thought of sitting on the side of the road with something I *could* have prevented does not thrill me at all.

Cant complain at preventative maintenance. Go for.

I knew my injectors needed of car cleaning when I would start the car and it would be a rough start and than blew alot of smoke.

The injectors were leaking alittle when the car was stationary....

Andrew from fuelinjector.com.au can do on-site fuel injector cleaning for under $40 an injector (plus costs for O-rings, dust seals, etc). That's if you remove them from the car yourself of course. He services the Melbourne area.

I have videos online available of the process I went through for my motorbike - it's the same for your car. Just go to YouTube and look up "KaldekBoch" in the search field.

I don't know if mine have ever been done, Its a AU2 XR8 its got 240K and it starts fine, except for the occasional, turn key, starter turns a fraction, pauses, then kicks over!
And that some mornings when the car is stone cold and i don't have time for the 1 minute warm up it hesitates as the clutch is just reaching the out position and so i dip the clutch and then its fine.
Should i be concerned? I ahve other things to tinker with the XR8 atm such as front brakes, and next up will be clutch, and by then my service will be due!

I just had a clean done, a upper engine carbon clean it was $98 in Toowoomba, he quoted $199 for injector clean and upper engine carbon clean. However as my car has had a bit of a surge problem he suggested doing the carbon clean first and see what happens. It made a huge difference, fuel economy is up and its more responsive and smoother. Still has surge though so we are going through one thing at a time. My car has 146,000 on it. Had injectors done at 120,000 at ford, it was $99 back in 2007
