Anyone else with the ISX 650 that has had a broken valve out there?
Bought the Magna with about 42,000 on it. Paperwork shows a broken valve on #6 at 19,032 miles in 2010 also included a new turbo.
At 20,XXX a new turbo was installed At 44,XXX the engine again dropped a valve in #6, which damaged 4 and 5. repair estimate is almost $29,000 and, again it includes a new turbo. Cummins NW has seen 4 of this failure, two on class 8 trucks and now two on motorhomes.
Cummins says it's a known problem and they have new heads and valves to address the problem.
Just wondering how many others have had this happen.
