I've been told the EGR is better off disabled anyway. No smogging of diesels (pre-1997) in CA so I should be in the clear.
The rust on my fuel injectors would suggest they haven't been replaced in awhile (or maybe ever). I've been thinking about ordering Monark nozzles from Mercedes Source, but would I be better off replacing the whole units? I don't know how they wear or how often they should be replaced.
