Injectors

[Stiffler318]

Hey guys i was wondering if there is anything i can do with my extremely noisey injectors??? there is hell of alot of tapping coming from them. (i was told that the tapping was injectors but i am only going by adivce, (i thought it was the tappets) but any ideads at all)

I have exactly the same problem with my car - drives me mad it does - my biggest dislike of the whole car in fact.

From what i gather from many previous threads on this subject, they're all like it to varying degrees. Some cars have very quiet injectors, like my other Touring, yet some are very noisy.

Some have experimented with injectors from different BMW cars, but the concensus has always been that this is a dangerous practice from the point that they can over-fuel, causing bore wash.

I'm just living with it for now until i can get a second set from a scappy and get them professionally cleaned/set-up in the hope they'll turn out quieter.

but i want to know, what is it that actually ticks?

is it the nozzle as it opens and closes or what, it drives me mad aswell

I think it's the solenoid which opens and closes the injector.

did u get sorted for a TB johnono?

Are you SURE its your injectors making a noise, and not your valve clearances being wrong?

Injectors...! Making a noise ??? Never heard of it !

[johnono]

Dan! yeah mate, daveT is sendin me one

Smi , pretty sure, this injector thing has been going on for aaages , so if it was pants it would have been exposed by now, got my clearances soeted 3 months ago, with the oil and coolant, so it shouldnt be in that department.. i hope

well i was told by a mech. that it was the injectors, and it looks like its just drawing blanks with ppl, i will have to try and make the car sound a bit more throatier and louder then i might not be able to hear it

I've installed 440cc/min injectors (stock is 149cc/min) , brand new outta the box and they STILL tick like a black sabbath drummer!!

My only advise, turn the stereo up and forget about them, they all tick, tis part of the design.

No cures for this, although other type/models may have a better/more upto date design's, but the std ones all tick.

HTH, Mark.

I could also be exhaust manifold, this makes a ticking noise.

To make sure, put a long screwdriver against the injector and the handle by your ear, then you will be able to tell exactly which ones are the loudest!

Be careful not to get sucked up by the fan though!
