Here is pictures after i washed the degreaser away with water:

(i took the rail of wires off after the battery was disconnected so i could get the brush and cloth in round the engine better, and made sure any water in the plugs got blew out)

but my question is see them wee pits where in the picture you see water, when i started cleaning they were mainly a black liquid, but i know my car isnt loosing oil or water because i check that every week and in the whole year they have been the same. Is there any chance the injectors are leaking fuel, are you ever meant to change seals?
