At this point I would like to say stop!!
I have never seen jammed or failed swirl flaps on a 651 engine, yet. (Please correct me if some have).
Common problems on the 651's are DPF pressure sensors, exhaust temp sensors (for which there is a modification to do the wiring loom in the event of either), snapped inlet manifold bolts, split turbo hoses and jammed EGRs.
