I have a 2022 ducato engine multijet 2.2D 16V 118Kw in my Adria camper. It is currently undergoing an engine rebuild. But now I have a problem getting the fuel injectors removed. They are REALLY tight! I mean really really tight!!! There seems to be some kind of design flaw in these new engines. Does anyone have any experience removing injectors on these newer engines? How do I get the injectors off? Does Fiat have a special tool for this?
Many more modern diesels have this problem, some were due to rain/water running into the engine compartment rusting them in to place , but often it is the combustion leaking past the injector seals in the cylinder head allowing a build up of carbon around the injectors.
I have used a slide hammer tool with the correct adapters to screw onto the tops of the injectors and eventually got them out, although not on your model.
There are expensive hydraulic tools available and even companies that specialise in that job who can come to your site in some areas.
I am not sure about a specific Fiat tool, however am I right in thinking your engine is the one used in Fords? In which case that may be an area to explore.
i Have used various penetrating oils and even a commercial steam cleaner to "melt" away some of the carbon, but in the end I got a cheap slide hammer tool with the correct adapters for make of injectors, from eBay and it has worked on several vehicles, so something like that may be worth looking into.
However a word of caution, the first one I did disturbed a tiny ceramic ball valve in the top of an injector resulting in me buying an exchange injector. Since then I learned more and that type of injector I was able to rebuild although too old to even see inside them properly these days, also later piezo type injectors are highly specialised so best left alone.
