Cummins Ism Exhaust Manifold Torque
One thing I dont recall when I put the turbo back on was if they were torque to yield bolts. I wouldn't think so, but I could be wrong.
At least it happened unloaded 30 miles out, unloaded, and I was able to keep feather pedaling it home but boy did it not run well under any boost, understandably. Mileage dropped a good bit too. At least it waited until I got out of the mountains... I'll end up replacing all 4 and the gasket for good measure. Is there a service life or anything I need to be aware of, torque to yield, or maybe it was just a bad stud?
