I had the same injector leak, and had the work done by a local deisel specialist.
Unfortunately they only cleaned the one injector (and the area around it) and not the whole top cover.
They told me that they use Mr. Muscle oven cleaner, although I have read the instructions on the tin, and it says DON'T use on aluminium!!

Another injector has started to leak, so I have bought the tool, and plan to have a go at the job myself (partly due to the cost of the first one)

I have had thoughts that either diesel or petrol will disolve the residule carbon, and I would think it would have the same effect on the foam, as this is probably a petroleum based product.
Worth a go, as if it don't work, you can just pour the rest in your tank, and maybe try some acetone (nail varnish remover) try ebay for that.

I hope this helps a little.

What did the residue look like, I think I have had/got a leak but it look solid treacle!!! It could not have got too hot as the plastic components haven’t melted!

Mercsys, between the plastic engine cover and the head is some noise dampening foam, when you get an injector leak (like I did) it melts and drips out the side and hardens to a shiny plastic.

Get thee to a nunnery/garage.

Not a cat in hells chance, am I going to take my Merc to a garage for a leaking injector. There is no trace of any foam in this area, there is the outer cover, with foam sealing beads along the edges, and under this is a fibrous mat but NO foam unless it is the glassy gloop in the well area around #1 injector!!! Though I have found that acetone goes for this goop in a big way, but it is nasty so all cautions apply, read the warnings…..

Hats of to the designer that specified a material that turns into a foul smelling mess as soon as it comes into contact with diesel.

It's to give you an early warning that your crappy common rail injection system is playing up again.

Olly and Jack @ PCS know what a properly caked engine looks like
