Injector clean is the way to go

Post Wed Apr 20, 2005 12:37 am

Just been onto a site which was recomended in this section, E30 diy ,dont know how to link it , maybe one of you will for me !

It was under the the heading "Injector cleaning" , Strange eh !
All is explained clearly , but i went a step further and where they just rinse with carb cleaner i hooked the injector up to a 12v supply,this meant the injector was fully open .
I then filled the injector with carb cleaner and blew an airline through it .
The spray pattern was transformed from a thickish mist to what i can only describe as a very fine mist !
This has resulted in an amazing difference in idling , and the response time has improved greatly , i used to get a bit of a pause before the revs came in , now its instant .
MPG may well improve also , if you have the means do it .

I had the injectors on my 323i cleaned in a proper injector cleaning machine thing. Aparrantly before I did it they were fairly dirty (I think they were the standard injectors after 155k miles). I didn't notice any difference after I got them cleaned

ive only ever had them done on an ultrasonic machine whilst still in place.

it isnt as good as removal and proper cleaning but certainly helps.

ive generally noticed a difference.

how difficult are they to remove , coz i have a bosch service center, and i think they can do it (if theyÃƒ”šÃ‚´re bosch type jects.)

was thinking of getting mine cleaned...saw this site advertised....anyone used them, know if they are any good, reasonable price etc?

i looked at taking them off and wondered if it was possible to get them out without removing the inlet manifold 'cos this looks light a right b*gg*er of a job. anyone know if i can get them out the easy way?

used to have a tvr griff and ultrasonic cleaning and setting up the injectors on a v8 was some of the best basic bhp impovements i spent my cash on....

Its easy to get the injectors off , just disconect both fuel pipes off the injector rail,take all the electrical plugs off the injectors , remove 4 bolts that hold the rail to manifold , take off bracket between rocker cover and manifold , then lift out rail , it does come out between rocker and manifold but it is very tight , if you want the least hassle possible take the rocker cover off first , its probably a good oppertunity to inspect your cam while your at it .
I got told that i should have had the injectors checked before i put them back in as i could have damaged them , it was too late as they had been put back in already , but as yet i have had no probs , so take it on at your own risk !
REMEMBER INJECTORS AINT CHEAP
Even if you just soak injectors overnight , safer method but probably as effective .
