Good afternoon  , I have a big problem ...

My 2017 ford edge been in the garage for nearly 6 months 3 months at local garage and 2.5 months at ford main dealer... I broke down on the motorway car just cut out so called breakdown out run few tests and said your high pressure pump is broken oh as well you have no coolant at all in your bottle... so that was strange anyway.

Got car toed to local garage that they changed fuel pump no problem but has a bad diesel knock  and cuts out with small inclines hills like its running on 3 cylinders ... car gas done 60,000 miles in the end ask ford dealer to help out so car was taken to local dealer to fix but ... they said they replace everything 4x injectors fuel rail new high pressure pump tank pump sensors etc... at a cost of £3,200 ...

After removing the injectors they found silver stuff on tip of cylinder 2 see pic , my concern is is this engine failure?  Can anyone tell me what this can be or where it has come from is this A failed injector ? Any info on this be greatful  it only appears on cylinder 2  thanks steve

I reckon there was coolant in that cylinder.

Have they done a compression test?

Hi thank you,  ford's say no need to do a compression test but I've already ask this to them hoping they do it ... 

They say its like a silver paste  kind regards steve 

Have they suggested a cause?

As all the coolant disappeared, I'd be expecting them to do both a cylinder compression test and a coolant pressure test.

The copper washer and the lower edge of the injector are both damaged as well if you look closely.  To me that suggests water trying to force it's way out during the compression stroke.  It could also be aluminum dust from the cylinder head corroding.

Hi yes finally had a cylinder test came back as OK on pressure as  the engine is cold .. so I'm guessing as it gets hot it would leak into cylinder 2.. so now engine is coming out a complete strip down and rebuild  thanks for your comment  help alot thanks just have to wait till ford's remove and send it away  .. kind regards
