I have a 09 Cummins ISX and it has split 5 timing actuators on the rear bank of cylinders in the last 4 months and no one can give me an explanation as to why. Any ideas out there

Bad injector on the rear bank or check valve in IFSM. Injector pushes fuel back in timing actuator with huge pressure and split it.

I’m having the same problem but it’s not my injectors I pulled the first three out and put in the back and pull the back three out put in the front still blowing the bolts on the same timing actuator replaced fuel regulators and rebuild the dampeners on the back of the IFSM this did not start until I put a new head on iT could it be a bad head it will break them between 250and 1000 miles

Try to run this test on hot engine because the temperature will open crack wider. -
Ok I’ll try it when it’s hot it didn’t have any bubbles when we did this the last time thanks for the help
Is there any thang else that could cause it in the ifsm -
