rickeieio Posted January 10, 2017 Report Share Posted January 10, 2017 Way back in 2014, on the way to Alaska, the trusty Cummins started shake'n and idling a little rough. We took it to Cummins NorthWest in Anchorage, where they did lots of tests, ran an overhead (adjusted valves and injectors) and proceeded to not tighten everything properly. That resulted in our limping back in a week later with a broken rocker shaft and some bent pushrods. Total bill was over $2500, and the roughness continued. I related that story here, and a Cummins employee who lives not too far away advised I take it to a shop near him, and provided the service manager's contact info. To say I procrastinated would be an understatement. So, the middle of last month, I took the Volvo to that shop and said, "fix it." Original estimate was for two new injectors and a total bill of around $3000. Good news was, it made 480 hp at the wheels, way over what you would expect from a 500 hp motor. I called and they said come pick it up. So, we're sitting in a restaurant with friends 1/2 mile from the shop, and the phone rings. It's the shop saying they're not happy with things. Hey, I just drove 100 miles to pick up our truck, and now you say it ain't ready? I'm not pleased either..... We headed over to the Cummins shop and I get to talk to John. After he explains some things, and asks some more questions, the faith meter for John has gone way up. This kid (hey, he's under 50) seems to be a mechanic, not a parts changer. I talked to John a few days later and they've tried replacing all the injectors and the actuators, only to have the problem persist. They even swapped a known good injector for one throwing a code, and the code stayed on the same cylinder......until they shut off the engine and restarted. Now, two weeks later, they've narrowed it down to the IFSM (Integrated Fuel System Management) plate, about $1,700. When John first threw that one at me, I did a bunch of research on it. Everything that controls the fuel on an ISX is attached to that plate. At least they put all my good parts back on so I won't have a massive parts bill, but the labor is "out of control", in the words of the shop guy I just spoke to. Merry Christmas to me............
