I have the VG30E engine. Three of the fuel injectors were bad (by resistance measurement). I am replacing all six while I'm in there.
I have removed the fuel delivery tubes that hold the injectors. The injector sockets or holders for cylinders 1,3, and 5 (firewall side of engine) are clean and shiny inside. The other three, for cylinders 2,4,and 6 (radiator side) have a fine uniform even deposit all over inside that gives the appearance of a matte finish, but is actually a deposit of some kind.
If I am not mistaken, the fuel flows through in the order 6,4,2,1,3,5 with the pressure regulator at the end of the line which surprised me. I expected the fuel pressure regulator at the entrance to the fuel tube.
What could have caused such a uniform deposit inside 2,4,and 6 and still leave not a trace inside 1,3, and 5 ???
Should I replace the pressure regulator as a routine maintenance item?
Thank you,
Richard
p.s.: It would be a challenge to photograph inside the injector sockets, but I could provide photos if it would help.
