New injectors OM603 advice please?
I would have thought the standard injectors meant for your engine would suffice for vegetable oil running - not heard of anyone setting these up for vegi fuel.
Engine generally employed in G-Wagens' are of lower compression if that is what you mean by variant. The engine number can decipher that. At a wild guess I think your engine code is either OM603.944 or OM603.928 or something like that.
Before changing your nozzles my suggestion would be to have these decarbonised to obtain a good spray pattern; I recommend the use of diesel injector cleaner as frequent use in diesel fuel as an additive.
What sounds are at idle? Sure just not leaky combustion chamber? Any excess smoke? Sure injector specialist will take money off you, but as Rakesh suggests maybe try a dose of Forte through it 1st.
I have as set of low miles injectors if you need any. 13,50 each
For veg oil different nozzles for spray pattern help but standard ones work with no noticable difference
Mine had done from 70k to 150 k with no issues
Sorry for late reply
They have done 89k
