In addition to installing the red warning light Cummins also de-tuned the engine. Doesn't really say how and by how much. But the ISL 400 may only be an ISL 350, or less? Part of the NTSA letter below;
6. Remedy program.
Cummins will recalibrate the engine control module. Additionally, Cummins will
enhance the Engine Protection System enabling it to provide early detection of the
failure mode and avoid more serious engine damage and resultant safety hazard. This
will involve installation of a new valve cover with a crankcase pressure sensor. Prior to
failure, the new crankcase pressure sensor will provide a signal to the dash with a red
light. A red lamp gives an indication to the driver to stop the engine as soon as it can
safely be done The campaign will be completed without charge to engine owners.
Cummins notes and emphasizes that all covered vehicles involved in the campaign were
sold with a 5- year or 100,000 mile warranty and are estimated to have extensive
warranty coverage remaining on these engines to cover future repairs as needed.

Cummins ISL Engine Recall
We still have the aluminum radiator in our 2007 Inspire with 80,000 miles and no indication of a problem yet. I did update the PTO to wet. Did it myself for less than $500.00.
