As FI mentioned, they should be tested periodically. My local guy cleans/tests/adjusts for IIRC $25/ea, then they're all balanced and known-good. Usually this is all that is needed, but they can wear out also.

edit: Some fuel problems will also kill them, an example being fuel conditioners that suspend water in the fuel, can cause corrosion if water/fuel solution is left in injectors when parked (hint: buy good fuel and let the filter do its job of separating water).

Just curious, where is your local guy located?

I recently rebuilt my injectors with Monark nozzles and could not believe the difference it made in smoothness and power. It was not a difficult job at all. I did not have them pop tested as I don't have access to a test unit. I have a non-turbo 617.

I rebuilt my injector nozzles with Monark. I also bought a hand-powered pop tester. The improvement in performance was very dramatic.

Dave's Diesel in Angola, IN, about 80miles from you (10miles from the MI line off I-69).

I believe that they have another store in IN also, just not sure where.
