Hi guys... took these out this morning what do you think?





The nozzles look pretty clean to me but I suppose its not till you take them apart?

Pictures added.... doh...

They come back from Injectortune looking(and performing)like new....

You're not trying to make them look pretty; you're trying to make them work like new. You can't tell anything of use by looking at them, and even if you clean what needs cleaning, they still won't be balanced, so send them off to injectortune.

Cheers Brian, thats the answer I was looking for.
Used to carbs you see, not really had to deal with injectors. I wasn't sure (from reading numerous articles) whether you could visually identify the condition.

On that note, probably worth taking the intake etc off for a clean a new gasket? The reason for me doing the injectors is I've been having the old kangaroo issue at low speed etc and everything else seems to check out at present. The cars done 130k so probably worth doing these bits anyway now do you think?

I suppose its where do you stop!

130k injectors will be leaning the mixture off quite a bit, and BMW designed the ECU software to run fairly lean at part throttle anyway. Lean + lean = kangaroo.
Might not be the only cause, but will be a major contributor.

Brianmoooore: What is meant by balancing the injectors?

So that they inject the same amount of fuel as each other for a given electrical pulse width, and, of course, the correct amount for that pulse width at a given pressure.
