Hi

I took the acoustic cover off the engine today to take a look at the injectors.... there seems to be quite a lot of diesel fuel at the base of the injectors...not sure if this is coming from one or more than one...

Could this leakback be casuing the error messages that I have posted ?

Is it likely that the rubber seals have failed.... is it worth replacing those on all injectors first to see if this resolves the rough idle ?

If so is there a how to replace the diesel o rings any where ??

Cheers

Gary
