Evening , firstly wd40 is about as much use as rice paper trousers in a storm .
Pure acetone & synthetic ATF as a 50/50 mix will penetrate the black junk holding the injectors into the head . The acetone softens the junk & draws the ATF with it ( to act as a lubricant ) . You need to break the bond created by the black gunk , before trying to remove the injector . Various firms sell engine specific reamers to clean the injector bore & seating face , it is pointless to half heartedly clean the bore & seat as you will only create a poor mating surface just begging to leak . As for no grease on the injector , I strongly recommend Febi white ceramic grease THINLY applied to the injector body & injector to copper seal face . The grease reduces any possibility of electrolytic corrosion or bonding due to injection by products blowing past the injector seal This is a very common issue with Mercedes CDi engines ( known as black death )

well I've had to admit defeat. Modified a wheel bearing impact socket to fit down over the injector body after removing the electrical bit (and the spring and other internal bits) which bore onto the fuel inlet to provide a turning input to break the stick.
With a FOUR FOOT bar on the socket I managed to get the injector (with a loud bang) to move a couple of degrees. I went back and forth a couple of times and the socket sheared. Multiple weldings and reinforcing of the socket later, the (one) injector was moving, through about twenty degrees but still needing the long bar, but it is now so mullered that it's impossible to get the socket to bear on it. The slide hammer is still completely ineffective. If it was the last injector I might have persevered (though I don't know what the next move would be), but as there are another two just as seized, I have decided the only way now is to butcher the plastic rocker cover off around them and probably replace the whole cylinder head. (hence my separate thread about part numbers) |

If you go down the remove cylinder head path , why not get a machine shop to machine the injectors from the head using carbide insert boring head . Injector internals are incredibly hard & a real bugger to machine , but it can work out cheaper than buying another cylinder head
Here's hoping & praying for you

Hi mate, check out SiRobb's video:

Interesting your problem with losing compression-would never have thought that was possible.
Lots of people referring me to that video, unfortunately, mine are way more seized than those Sirobb is dealing with. He says very early on in the process something like 'you can see there's a little bit of movement'. Well. Refer to my above mention of a four foot bar and all my strength....There is absolutely NO give in these. However.With the rocker cover removed (in a thousand pieces) I can now get our special tool onto the exposed injectors and am going to get back to work on them. Maybe the cylinder head can still be saved. |

I'm also thinking about putting the blowtorch on it, as there's no plastic to melt any more :-) Any thoughts on that?

No progress. Does anyone know if it's possible to hire one of the hydraulic removal tools?

This is merciless, but be sure to protect the engine cover so it doesn't crack, etc.
Also, it's good to go SLOWLY, to allow time for the sludge to break up https://www.youtube.com/watch?v=5tcAHBhSx8o

OP
Wont it be cheaper/quicker in the long run to get someone in to do it for you? There are specialists who will come out and do the removal - or so they say - on site. No idea about costs. http://www.seized-injector.co.uk/ Oxfordshire based. I just googled that. There seem to be a few around. It might save you a lot of agro. |
