Photographic Hall of Horrors
This is our Photographic Hall of Horrors
or whoops should i really have done it like that !!!!
Most of these Photos are injectors damaged by previous attempts at removal before A P Autodiagnostics Ltd were called in to successfully remove them....
The rest are there for your interest and possibly even entertainment !!!
More M9R Solenoid and Piezo injectors suffering from the design fault where water leaks onto the injectors, there is a drain built into the cylinder head / cam cover but unfortunately
due to bad design it is too high up and allows the water to build up and collect around the injectors, holding it there to corrode the injectors over time causing significant damage and
destroying injectors and clamp bolts leaving vehicle owners with large bills for repair. there is a modification to the vehicle which reduces the amount of water getting onto the injectors
and this modification is mandatory for any warranty to be upheld but due to British weather being damp most of the year the injectors still corrode into place and warranties are being
voided due to external corrosion on the injectors being visible.
You can clearly see the water build up in these photos and the damage that can be caused the later solenoid injectors with severe corrosion have just rotted away, again this
issue on the later engines has yet to be acknowledged by the manufactures as an issue and although the vehicle modification from the older model can be applied to the later
one it still fails to stop all of the corrosion from being caused and stopping its results.
This was an M9R Piezo injector before destruction ! This used to be a Citroen C8 Injector ! Remains of a Chrysler Voyager injector !
These two photos show an M9R Piezo injector damaged with the dealer type tool (threads torn off) This shows the Second of three M9R Injectors in a bare cylinder head

This is a 1.3cdti Corsa engine injector as you can see it These two [pictures show the build up of "Black Death" carbon from exhaust gasses
suffered heavily before we removed it due to injector seal leakage being left to do its work without prompt repairs on a
Mercedes sprinter 113 engined van, These jobs require a considerable amount of
extra time spent on them cleaning prior to injector removal. a point to note is that the
injector leak off pipes and the electrical connectors can effectively be glued in place
by the carbon build up meaning the only option is to break them during removal.
This is another injector in a Mercedes, only This image shows some of the many ways in which an M9R This injector is out of a Honda accord 2.2ltr engine. Note

expensive cam cover.
These three photos show how bad the corrosion can get on the M9R engine. Note the sand like corrosion almost burying injector clamps, and the damage done when trying to extract the injector with the
wrong tools and no expierience !!. finally note the broken clamp bolts sheared off just below the surface in the last picture.

Another failed idea on how to remove a seized injector This image shows three clamp bolts from the M9R engine The top bolt was shortened rather than clean out the bolt hole

This Glow Plug removal was attempted by a customer who learned to regret his attempt to save himself a few pounds.
if you look closely at the second picture you can see where the guy managed to smash a lump out of his cylinder head,
unfortunately causing major damage in the process.

We can sometimes repair this damage with a specially adapted seal which we make
specifically for each individual engine, which we still managed to do in this case saving
a relatively good vehicle which otherwise would have been scrapped.
Its not very often we see a new idea for injector removal This 12 plate M9R engine was suffering from the usual water collecting around the injectors rotting away the injector

didn't work so we were called out to rectify the issue.
The injectors on the left came from the engine on the right, They were extremely tight taking in excess of 20 tons of force to remove them. the first one snapped near the bottom of the hole
but this didn't present an issue as we have dealt with this many times over the years. The engine was a 3ltr Iveco unit.
Both of the above images show removal attempts by threading a bolt into the remains of the injector, the first a Jaguar "F" Type V6 petrol had been extensively hammered in an attempt to shock it free
cracking the cylinder head in the process and costing the customer greatly, The second was a ford transit, A "mechanic" at this large hire company had welded a bolt to the end of some threaded rod and
screwed it into the injector remains, as soon as force was applied the weld broke leaving the bolt securely fastened into the nozzle and the nozzle securely fastened into the head. (at this point we must
point out that in both cases were not the ones who did the dastardly deed).
Every now and again we get an odd ball job to do and this was a nearly new Nissan NV400 van with barely 3000 miles on the clock, yes you read it right 3000 miles from new. two injectors were badly seized
in and took considerable force to remove them, it doesn't bear thinking about what this would be like in another 50,000 miles or so
Although A P Autodiagnostics were successful in removing many of the above injectors, We strongly recommend that you don't abuse your injectors to this extent before calling us.
Not only does it make our job more difficult but it can also increases your costs quite dramatically in some cases!!!
