VR6 Injectors

[davmatt 0]

Apologies if this is on here but ive spent an hour looking and cant find anything so.......

 

My local garage have said two of my injectors are blocked and coil pack needs replacing

 

So...

 

Do i fit new injectors or have the old ones cleaned

Can i do it myself

 

if so is there a thread on her that tells me how? I'm mechanically competent but if someone has done it and written it up i'd be an idiot not to take their advice. I have been unable to find this stuff on here already but as i say my apologies if it is, there's just so much on here.

You need to have the injectors professionally cleaned. Try finding a Bosch injector service centre, or a local deisel specialist, they should see you right.

Thats a good idea. New injectors are £97+VAT each from Volkswagen so trying to clean them before having to replace them is a good idea.

 

Also take care of the little o-rings that the injectors fit into - those are £2.35 each from Volkswagen and you need two per injector... I should know as I've just paid almost £30 for a full set of 12 of them :(

£97 each?!!

 

You can buy a set of Delphis for not far off that, and they idle 10 times better than Bosch injectors.

£97 each - that's the price they quoted me.

 

Fortunately for me there are lots of people about now with supercharged VR6's, who all magically seem to have spare sets of injectors available :D

So...

 

Currently, based on the fact that i'm relativly poor and i dont trust garages (i particularly dont trust random Bosch 'specialists' to take of the top of my engine, i know its only the inlet but VW couldnt manage it without breaking everything in sitght) it would seem that if i bought a set of Delphi Injectors i would have minimum down time (new for old swop) at an acceptable cost.

 

But the question still remains, do i just 'take it all apart', screw new injectors and o rings in and 'put it back together (the part a haynes manual usefully refers to as 'the opposite of taking it apart, hmmm!).

 

Or am i being optomistic?

My suggestion was for getting the injectors cleaned. Not getting the engine stripped down there.

 

Next time I won't bother.

Yeah plenty of original injectors kicking around as pointed out already, so there's certainly no harm in sticking some in to see if it cures the problem.

 

They are very easy to replace - once you take the manifold off :lol:

 

It's basic nuts and bolts stuff, you can't go wrong tbh......and I would do it with the engine warm as it softens the O rings, otherwise they can be a pig to get in / out of the engine. If they are, a dash of vaseline helps....or soaking the O rings in petrol for 30 mins.

[KADVR6 0]

vaseline eh Kev, so thats how you occupy yourself when not messing on the car eh???? :lol:

[Kevin Bacon 5]

Every good mechanic will have tub of Vas in his box :lol:

 

What I want to know is, how the heck did someone come to the conclusion that petroleum jelly is a good thing to rub onto cracked lips (the ones on your face, that is!) and for lubricating......

 

.....battery posts and injector O rings :lol:

Apologies to Toad for an unintenionally curt response, but as you didnt confirm my second question i.e. can i do it myself, i took the reply to mean i couldnt and needed to take it to a garage for them to do all of it and at that point i was unclear as to how big a job this was. Apologies again for any offence caused.

 

Thanks for the offer of the injectors Karl i'll take you up on those, where do i send the cheque to?

 

Access notwithstanding it sounds as though i just remove enough bits to give me access to the rail, fingers crossed that all the gaskets come away intact?

 

Any further wisdom would still be most welcome.

hi

its pretty easy to change the injectors when the inlet manifolds removed and also best to change the injector seals £2.35 each is shocking just get the measurments from vw and call your local seal shop "arf arf" theres one in stafford on the marston road called gpt seals 01785 259423 thats where i got mine from at a proper price for a small rubber ring just make sure they are suitable for fuel usage! i think its viton they use or something like that! theyre great any seal any size give them a bell!

I cleaned my injectors last week, car runs superbly now... idle is absolutely rock solid

 

What you need is an ultrasonic cleaner from maplin / ebay.. for around £25

 

This is the one I bought...

Fill it up with meths and put them on for 3-4 cycles each. You will see all the crud inside the injector dissolve and stream out.

 

(Meths is a good choice as it will evaporate totally and not leave any moisture inside)

 

Dry them off on some kitchen towel and leave to dry overnight to let any residues disappear.

 

Couldn't believe the difference after I refitted them... engine fires instantly now and I am getting 20mpg around central london (was 13mpg last week!)

 

Alternatively, pull them out and send them to me and I will do them for you free of charge mate.
