Gti 8v injectors
Gti 8v injectors
Does anyone have either:
1) a known good set of 8v injectors
or
2) any ideas where I can get new pintle caps and o-rings for mine?
I am in Bristol, UK. The specialists I have tried all want to recon them for me, but I am trying to keep the costs down!
I have considered all the great advice for my lumpy running 8v, and want to reinstate the original injectors asap. I think you are all correct regarding rich running, and I need to eliminate this first.
Thanks All

Re: Gti 8v injectors
Go to a Lucas Centre (or Bosch) nearest you and they will do a service on the injectors. The injectors are pulsed in an ultrasonic cleaner, tested in the rig and finally equipped with new filters, caps & 'o' rings.DS Andy wrote: 2) any ideas where I can get new pintle caps and o-rings for mine?
It cost me £60 for all 4 (they are also tested for balance) and is the best £60 I have ever spent on a car!

Yes you are right, it was 4 months ago (ie last October, I hadn't noticed) !
These machines for the clean/test/service of injectors presumably are available with others for the provision of this service to us and the motor trade though (besides Bosch)?Euro wrote:After a considerable amount of non-stop work and investment into LSUK over the past 5 days, the Euro Car Parts directors realised that they had no option but to place LSUK into administration with effect from Monday 6th October 2008.

I had mine cleaned, posted them on Wednesday afternoon, and they arrived home clean on Friday morning!
I am very happy with the result.
Engine runs smoother and revs more freely now.
Cost about £50 all in.

It might be clever now, but it won't be in the morning!

A cheaper way to clean injectors that may help the budget which I have and found works well at about every 20-30k. Also gives you a good idea of any really duff ones.
Using a spray can of carb cleaner. Place the injectors upright in a small container, add cleaner to cover the caps and fill the top inlet. Leave to stand for a couple of hours, remove and clean with a small tooth brush, especially around the inside of the cap.
Using compressed air, set the delivery pressure to 30 psi, which is approx 10-15 psi below fuel delivery pressure.
Find a 4-5” length of garden/pvc type hose that fits tightly over the cap and body (hot water works) and lightly secure with a jubilee clip.
Using about a 2mtr. Length of twin light gauge cable – (say 5amp) connect to a PP9 - 9 volt battery, with any electrical switch, inline, placed near to the battery, and to any one of the wires. Fit two miniature female spade type (speaker) crimps and connect to the injector. 8 and 16v Injectors are not polarity conscious.
Fill the short length of hose with cleaner, keep hose and injector facing downwards to avoid any backflow of fluid into air lines, connect the air line, this pressure should lift the valve, if not, operate switch in very short bursts until all cleaner is expelled.
One very, VERY important safety rule with this operation. Carburettor cleaner is highly flammable, mixed with compressed air, generates an explosive vapour mixture.
Operate in the open/free air only, clear of any electrical equipment, bulbs, fluorescent tubes, hot exhausts, smoking etc.etc. Also clear of face and hands.
Refill hose and connect to inlet side of injector, operating in line switch, again in short bursts. Repeat both sides if necessary.
Once you’ve cleaned a couple, you can get an idea of the general spray pattern appearance. Placing sheets of A4 paper, directly under an upright injector, about 3-5” away, should give you an indication of any irregularities within pattern.
Using just compressed air connected to the inlet side of a closed injector, place the tip into water to check for any major valve seating faults. You can also refill the short tube and pressurise, to test for a closed drip rate at the nozzle.
When refitting, apply a film of grease to O rings, fuel rail and manifold sockets.
If the O rings are damaged I quite agree with Mike at that price. The last time I brought 4 sets of top and bottom seals, £23.00 - Made of gold -and the last time.

Reminds me of a little while ago when I was changing the fuel filter on the valver.prm wrote:One very, VERY important safety rule with this operation. Carburettor cleaner is highly flammable, mixed with compressed air, generates an explosive vapour mixture.

Had a rolly on the go (as usual) and didn't think about it until I had the filter in my hand inches away from a burning fag.
The penny then dropped and I slung the fag over the wall a bit sharpish. No explosion though happily.
Or the time I had dropped a fuel tank out of a scrapper BX, and ended up wearing the remaining contents of the tank, then fired a smoke up, didn't think about it then either, until I reached up to grab a rag and the end of the fag contacted with the arm of the overalls and they went up.
Smoking really does kill ya know.
Smokes lots, because enough's enough already!
Far too many BX's, a bus, an ambulance a few trucks, not enough time and never enough cash...

There is a difference. With early 8 valve engines the injectors with a Jetronic ECU system, are, Bosch No. 0 280 150 734.
Then changed to 0 280.150 762, the same as a 16v, possibly with a variant of the Jetronic set-up.
Most probably the ECU/AFM and fuel delivery pressure were adjusted to give an alternative duration and spray pattern for the 8 valve engine.
I believe the 762 injector number stayed the same, even with the changes of Motronic ECU unit on the 16v, but not sure with the late air-con cat models.

Dear all,
thanks for the input - I found a local specialist -with Docs help, but unfortunately for me, 1 out of the 4 injectors is knackered. These are different to the 16v MI16 injectors, does anyone have a couple of spares for £££ as a replacement from Bosch is £85.
I know Doc said he has some somewhere, but he isn't sure he can find them easily. If it helps I will get the part number.
Thanks All!
Andy

The 'specialist' told me this on mine but I asked to see as I measured the coils before taking them in and they were OK for this measurement.
He showed me the injector that was not working under the pulsing of the machine & I took a spanner and smacked the metal body of the injector and it sprang instantly to life. Clearly some gunge was sticking it and once free and cleaned it has given no further trouble.

Thanks Way 2 Go - seriously speedy response!
Unfortunately the faulty injector is clear of gunky deposits, but squirts twice the measured dose it should! It was obviously heat damaged when I removed it - the o-rings were split and the pintle cap/heat shield was melted.
The specialist I used is well-respected locally, and I don't doubt them, they showed me the price for the replacement and were most apologetic! They've even said they'll test any spare I can find for no extra. They are going to charge me £15 each for the 4 they have done.
If anyone is interested, they are called Tom Day Ltd and are in Keynsham nr Bristol - but I still need one or two spare injectors, so I can use the best 4!

Hi DS Andy,
£15 per injector seems to be about the going rate! No reflection on your specialist intended but should be available country wide and on the net.
If faulty on the metering test, thats a different matter so long as like is being tested against like and the ultrasonic cleaning has been run through more than 1 cycle.
They tested mine for metering (before) after stripping off the filters and pintle caps and they were uneven but after cleaning they were pretty close I must say. It was only after cleaning and they passed the metering test that they replaced the filters and pintle caps plus of course the 'O' rings.
