Many of you are probably aware by now that Cummins is recalling their ISL diesels produced between 10/17/2005 and 4/18/2006 because some (presumably only a few?) may have connecting rod wrist pin failures that will result in a seized engine. Rather than rebuilding all the engines when many will never need it, Cummins is installing a sensor to warn if a failure is imminent. An owner who had the recall remedy done at a Freightliner shop reports this:
They give you a new valve cover with a sensor mounted in it. The sensor is wired to the ECM and the ECM programed to pickup excessive blow by measurements from the sensor. This is supposed to give you a "STOP ENGINE" signal and shut you down before the engine blows up.
It remains unclear whether there is any early warning or you will suddenly find your engine shutting down as you drive along the highway somewhere (hopefully not too far from a shop and not in the middle of downtown traffic!). Engines failing the sensor test or actually seizing up as a result of the failure will, of course, be rebuilt under warranty.
