Hi,
I am about to carry out my first injector seat copper washer change. I have all the bits but I need a heads up on the best tool to clean the injector seat in the head. There are general purpose kits around but I don't know what the reqired diameter is yet and as I dont intend to be doing this on other vehicles is there a "good" tool that is for the Puma 2.4L. I'd rather pay a little more for a "proper" tool instead of buying a cheap general purpose chinese tool. If you've used a good tool could you please let me know or even better post a link. Thanks!!  |

If you want good tools, stick with Sykes Pickavant for this sort of thing.
https://sykes-pickavant.com/collections/injector-service For TDCi and TD5 I use 1745000 and 1750000. Circa £200-ish for the pair. I note that there is also now 017500v2 which seems to be a combination of the two above at about the same price as the two above together but of which I have no experience. |

Literally just done this too, I used the Laser 6101 kit and it worked a treat. Running so much better. If you were nearby Stroud you could defo have borrowed my kit 2.4TDCI 90 - everyday brilliance

Bod
That looks identical to the Laser tools one, did the job and is 1/4 price, so even better 2.4TDCI 90 - everyday brilliance

Thanks everyone, it's good to hear from people who've done the job. My garage quoted me £600! So I'm hoping to save some money as well as making sure the job is done properly.
Are there any useful tips on the process? I intend to take off the rocker cover and clean that as well, as I've read that the breathers can get blocked. |

This is a job that needs doing on SWMBO's 2.4 but I must admit I'm a bit wary of it.. by the time I've assembled the tools and had a faff about I'll probably be wishing I had a garage do it. One of the bits that confuses me is this:
"make sure that you plug the hole leading into the cylinder straight away to prevent anything falling in" How on earth do you plug that hole, but then also use a power tool to clean the seal seat, as that surely has to go across the hole too? does the plug sit lower down than the seal face? |

The laser kit i bought comes with plugs and a threaded pole to put them in/out. I didn't remove rocker cover, just did injectors.
I too was putting it off and dreading it, but found it surprising simple and satisfying. Only had 1 injector that was a bit hard to get out. 1 looked fab, 1 was well grubby, 2 moderately grubby. So defo needed doing, the tappety noise has gone and my provent crankcase catch can has very little coming out of it now. Having the bonnet vertical (bungee’d to the rafters 👍) made it easier, it is a bit of work out. The LRM instructions and pics were easy to follow and adapt to cleaning not replacing.

Yes the hole and plug are a bit lower than the seat, although if you get too enthusiastic with the brush it will pick up the plug, so be careful as you take the brush out. I used paper towel wrapped around the pole thing from the kit to clean the crud out. 2.4TDCI 90 - everyday brilliance

Thanks very much for the tips
I think I'd have to get the rocker cover off as well and have a good clean. One of ways I thought that there was an injector seal issue is that there was a hot oil smell coming in with the heater blower when the engine was warm, and having a look about, I could see there is a slight misting of oil coming out of the rocker cover gasket on that side of the engine. A bit of duct tape around the ridiculously poor fit of the heater air intake join has solved the smell in the short term, but looking at things like this: (skip to 4m56s ) ...really confirm to me that I should get the rocker off as well. |

If you look at the image below you will see six little threaded things in the lower centre of the photo. These are cylindrical with a very small flange on one end and a blind threaded hole in the flanged end (in some ways like a blind Rivnut) and yu screw one of these lossely onto the end of the threaded rod which is just above them in the photo. You then use the rod to insert the cylindrical plug into the hole that the tip of the injector pokes through into the combustion chamber or cylinder, and unscrew the rod from the plug. The result is that the crud you are about to remove from the injector seat and the recess for the injector body cannot fall through into the cylinder. Once you have thoroughly cleaned the injector recess (with the suitable size brush from the three on the left of the photo) and the injector seat (with the suitable sized brush from the two at lower right) and then removed any loose crud (if using a vacuum or airline hold the plug in place with the threaded rod first), you can then remove the plug by screwing the threaded rod back on and extracting it. The brushes are rotated with an electric drill using the flexible shaft (between the threaded rod and the thinnest (long) brush in the photo). The final step if necessary is to use the very thin brush at the top of the photo to clean the hole the plug was in, and for this you apply grease to the brush to that any displaced crud sticks to the brush. It is unlikely by this stage that anything likely to damage the pistons, bores, or head will fall in during the final stage. Hope this makes sense!  Click image to enlarge |
