This is a Cummins Job. So your dog and you are out of the woods. From my understanding, the Cummings 0953 campaign effects the ISC, and larger engines. It includes ECM reprogramming and checking blowby pressure to look for defective valve seals that made their way into some engines. Most people are reporting 4-5 inches of blowby. Up to 11 is normal. Mine came in at .7 , well within limits. But, my engine did receive a new Turbo due to the Turbo re-clocking campaign, so that may have contributed to my "good" numbers. It was not able to be re-clocked so a new Turbo was installed under warranty. We try to stay up on all the updates. I was informed that I would get better mileage from the ECM reprogramming and have found it to be true.
