We had an intermittent problem with a sticky intake valve on the Wright R-2600 14 cylinder rotary engine powering our TBM torpedo bomber. When it stuck, combustion gases would blast into the intake manifold, the engine would immediately die, and things got really quiet and scary. It would start right back up, but that doesn't make it ok. We fired it up on the ground and slowly fed Marvel Mystery Oil through the carburetor air intake. It seemed to help. A rebuild occurred in the near future.
