  • Injector removal.

    We've traced the problem with my Monty to a dodgy injector.

    Excellent I hear you cry... well it would be, bar the fact the injectors in my spare lump are well wedged in the head due, according to Haynes, to carbon deposits.

    They recommend an 'injector slidehammer' to get them out - anyone know of anywhere that sells this apparently specific tool.

    Also, I, if I can get them done reasonably cheaply, will get the 'new' injectors cleaned before they are inserted in the head, so any recommendations on somewhere to get this done?

    I had to make my own last time I needed one (for a Transit). Find a nut which fits the thread of the top of the injector. Weld a bar in line with it, slide a lump over the bar and weld another nut on the far end.
    Use as expected.

      Halfords do one you may need to go to a main Halfords rather than a smaller shop, but they do have them.

            I had this problem.

            What you need is, lots of penatrating oil, and a large spanner, and a hammer. Soak the injectors in penetrating oil, get the spanner on the flats of the injector and get them turning, if nessacerry using the hammer to clout the spanner round. It may take a long time, but once theyre turning, grip a pair of mole grips on to the flats, then twist and pull until they come out.

            When you refit them, USE NEW SEAT WASHERS I didn't, and paid the price, and spent a day running round trying to get some, as the pistons would just blow the contents of the cylinder out from around the injector where they wern't sealed properly.

            Lucas will re-condition injectors, it costs £25 per injector, or so I was quoted.

            If the injectors are really really stuck in, then a slide hammer will probably obliterate the thread in the top, its a risk but you may be lucky.

              My local diesel place will test them for £2 each and if you have any work done on them they'll knock that off of the bill. I think I was quoted 25 quid ish each to have new nozzles fitted and the pressures recalibrated.

                That sounds very, very reasonable to me, given how much the local lot have been hinting at - £50+ per injector to ultrasonically clean.

                If you could PM me the contact details etc., I'll get in touch with them.

                Many Thanks!

                  It certainly does - all noted, and I'll try that before resorting to more tool purchases, when I finally recover the car on Saturday.

                  Cheers

                    Just to update this thread on a useful tool to extract hard-to-extract petrol injectors. Mine had been in for 26 years since new, with engine running very poorly on petrol. I decided to change fuel filter and injectors myself after being quoted well over £100 by a garage, just for the labour. Fuel filter was easy. Injectors would not budge from the cylinder block though. I cut out a basic tool especially for the job, starting from a 250mm BonsaiBar by Roughneck which I obtained from TravisPerkins for just over £8. I used an angle grinder to grind out the shape of the bottom of the injector into the flat part. Then positioned the bar at the bottom of each injector in turn and hit the end of the bar with my hand. Eventually all injectors came out using this method, without any damage to the injector. Below is pic of my bespoke bonsaibar, and another pic of my extracted injectors, all filthy and carbonized at the end. One of the end caps of the injectors had also broken.

                        I love it when someone re-purposes an existing tool. Will take a trip to Travis Perkins and get one.

                        Well done.

                          Also took some photos of my old fuel filter inside, as contrasted with what a new one should look like. It was pretty bad. Car is running much better now, unsurprisingly.
