Hey jack. The bear had a few, RCMP had one on takeoff, and I know of another that was found making metal and was pulled out just in time. I've logged over 2000 hrs of PIC and never had engine problems. A different way of planning and executing approaches, climbouts, etc makes one feel more secure. But, if you aren't comfortable flying a single IFR then you shouldn't be flying one period. Great aircraft, not too bad engine.
