leaking injectors
 

i have fuel residue around the first two injectors on my 1981 300 CD and am wondering how to fix it. should i do all five or just the ones leaking? ndo they need to be recalibrated? what seals them and how hard is the job. i cannot see a visable leak but there is fuel around them and i can smell it when i open the hood. any help is appreciated

You should be able to get away with just replacing the gaskets. They're very cheap so I'd do all 5

Check the condition of your overflow lines - they might be weeping fuel. If in doubt replace all of the segments with OEM German style rubber hoses with the grey fabric covering. Could save you lots of time not to mention the hassle of messing with the hard lines.
